Ask the Vet: Ho-Ho-Holidays!–and Your Pets

by petloverunplugged on October 27, 2009

Robert asked: What is the best way to keep my pet safe during the holiday season, and what are the hazards I should be most concerned about?

The holiday season is the most wonderful time of the year so here are a few tips to ensure that you don’t ruin it for you and your pet. I can remember my first Christmas with our new Rottweiler puppy Alf.  He arrived on December 22 at 8 weeks old and 16 lbs  of energy and curiosity.  The minute he entered the house he chased the cat into the living room and proceed directly to the Christmas tree which he then promptly pulled over. No one was hurt but it immediately made me painfully aware that we had to make changes to our holiday preparedness now that we had a new pet in the house.

Both cats and dogs can find trouble on the Christmas tree so make sure that tinsel and curly ribbons are avoided or high enough up on the tree that they cannot be grabbed. This is a particular problem for cats as they love to play with shinny things. Remember that cats often eat things like thread ( read tinsel or ribbons) which can get wrapped around the base of their tongues and the other end can find its way into the stomach. This can cause major problems for your cat. Just remember that all low hanging ornaments can pose a hazard for your pet so get them up higher and choose your ornaments with your pets in mind.

Another potential problem with Christmas trees is the water in the tree stand. This is particular problematic for small dogs and cats as the water in the stand can be poisonous from preservatives, bacteria or other residues. Cover the tree stand and avoid some nasty GI upset or worse.

Outdoor hazards in the Pacific northwest include slug bait, compost piles and garden mulch from leaves and grass clippings, lawn fertilizers, herbicides and insecticides and mushrooms. If you do treat your lawn with any chemical substance keep your pets off the lawn and rinse their feet off if they come in contact with treated lawns or gardens.  Also watch out for slug bait, dogs love it and it is VERY toxic. Use small amounts of beer to kill slugs. It works and small amounts won’t hurt your dog.

Potentially the most lethal and common danger is antifreeze/coolant. Many of us change our coolant in the fall and spills occur and even small amounts of antifreeze/coolant can be toxic to your pet causing kidney failure. Sadly our cats and dogs can’t seem to resist the “sweet” taste of antifreeze so please watch out for coolant leaks and wipe up any amount you see on your driveway or on the street. If your pet ingests any call or see your veterinarian immediately.

Another indoor hazard found in the kitchen that almost no one knows about is xylitol.litXXylitol is the “latest” diet product to enter the mass market of consumer food products. Xylitol is a sugar alcohol – an artificial sweetener from birch, raspberries, plums and corn. This product is found in many human “sugar free” products such as gum, candy and other sweets. In humans, high doses may have  laxative effect, but in dogs, ingestion could be fatal.  Xylitol can also be found in toothpastes, sugar free gums, low-carb baked goods and desserts. It is also becoming more common in cooking products so check the packaging before you let your dog “lick out the bowl.” Check out these websites for more information on the toxicity of Xylitol:

http://vetmedicine.about.com

http://www2.aspca.org/site

Here are two other articles I’ve prepared for my clients on toxins in general and Xylitol in particular.

Prevention is the Key with Toxins and Xylitol – Toxic to Your Dog

If your veterinarian is closed and you suspect your pet has been poisoned you can call the National Animal Poison Control line at 1-888-426-4435 7 days a week 24 hours a day. This is a fee for service line so have your credit card handy.

Another of the most well know pet toxins during the holiday season is chocolate. While not near as toxic as xylitol, dark chocolate can pose a real health treat to your dog. For more details on chocolate poisoning click here to read more.

If you have any other questions about potential toxins let me know and I’ll be happy to answer them.

Debbie, from Salem, Oregon asks: Why are my vet bills so high and increasing every year even though I  just require basic care for my cat?

Admittedly veterinary cost are rising and like human medicine  it is rising faster than the rate of inflation. The reasons are numerous, many beyond the control of the practice owner and a few within her control.  We run a low cost practice in Oregon so keeping our prices affordable is of paramount importance to us and our clients. We purchased our first practice in September 1995, and back then general health exams were $9.50 and a cat neuter was only$19.95, clavamox drops cost us $2.50 a box . A few years later Advantage for cats came on the market and cost us approximately $16.50 for a 4 pack.  Fourteen years later the price of clavamox has increased more than 400% (yes I said 400%), in 10 years Advantage has increased 250%, our own health care costs have increased more than 300% yet the wages of newly graduated veterinarians have increased only 3% annually over the same period of time while their level of indebtedness, primarily due to enormous student loans, has more than doubled.  And that trend is continuing. This morning (11-16-09) on CNBC it was reported that drug prices have increased by 9.5% so far in 2009 – with inflation less than 3% the big pharmaceutical companies are right on tract for another 300% + increase this year. So we know that the  new, young veterinarians coming out of America’s vet schools aren’t driving the cost of vet medicine up -so what else is?

Part of the blame falls squarely on the shoulders of the pharmaceutical companies, whose costs have annually increased at rates 2 and 3 times that of inflation, even for drugs that no longer carry patents. While the price of many drugs has dropped thanks to generic manufacturers there is still very little competition in the “pet specific” drug market due to the  relatively small size of the veterinary market when compared to human medicine and the dominance of one or two giant multinational corporations. In addition, even some generic drugs can fluctuate greatly in price if one of the generic manufacturers drops a specific drug due to lower margins. A clear example is cephalexin, a commonly used drug for skin infections that has been off patents for more than 20 years.  This is a human medication widely used in veterinary medicine so the veterinary market has very little, if any influence over the price of the drug. In the late 1990′s there were commonly 2 or more suppliers of cephalexin so the price varied around $60.00 to $75.00 for a 500 count bottle of 500mg capsules. But when a new generic competitor entered the market the price quickly dropped to $49.95 for the same bottle. We were ecstatic but it didn’t last for long. One competitor dropped out of the market and the price suddenly jumped from $49.95 a bottle to $149.95. I couldn’t believe it! The sales reps cited supply and demand and lack of competition, thankfully, the price did drop back down but I knew from that point on that the actual “cost” of the drug had little if anything to do with the price the pharmaceutical companies sold the drugs to veterinarians or their small suppliers and distributors. The pharmaceutical companies ability to set prices rules the market place, not the true costs to develop and manufacture the drugs.

So if the price of drug treatment has gone up so much consumers could assume that veterinarians are making more on drugs now than they were in 1995. But they would be wrong – dead wrong. Higher drugs prices have caused most if not all veterinarians to lower their margins on all drugs sold to their clients to buffer them from “rampant pharmaceutical inflation.” In addition, web based pharmacies like 1-800-PetMeds has dealt a double blow to veterinarians. First margins on all products from pharmaceuticals to fleas control have dropped dramatically and many clients are now purchasing their medications online, further reducing  profits at all veterinary hospitals. The result was a major drop in an important profit center in most veterinary hospitals. Hospital owners had to do something to make up the difference. If veterinary hospital owners wanted to maintain their current profit levels they had only one option – raise the costs of the services they provided. And we did – but did we increase our profits? Sadly, no, we are just treading water. So in this case consumers are partly to blame for the increase in veterinary fees. Consumers have reduced the profits of their local veterinarians and given those profits to publicly traded companies that contribute nothing to their local community, unlike their local veterinarian. This situation is not unlike American manufacturing in general – we are complaining that jobs are leaving America but we all want the lower prices that cheap imported products provide.

Another major contributor to the escalating price syndrome is consumers and hospital owners addiction to new facilities and technologies. Veterinary hospitals are getting larger and stuffed with the latest in technology all in the pursuit of an every increasing “standard of care” that vet medicine is pushing. This push for improved “Standard of Care” is coming from two place: first from consumers, as we encourage them to view their pets as an integral part of the family, at least a segment of the pet-owning population expects far more from their veterinarian as they see advancement in human medicine with at least some of these clients willing and able to pay for these advanced procedures. The second push for improved medicine is coming from the Veterinary Medical Licensing Boards and veterinary accreditation bodies such as the American Animal Hospital Association (AAHA). Collectively they are mandating improved procedures, more equipment, upgrading of facilities, all sorts of changes, that really are good for the underlying quality of the service, the medical care we perform, but definitely contribute to escalating costs. Consumers like new facilities and technology and hospital owners feel they need to provide those facilities to keep or attract both clients and new graduates – but I firmly believe that this pursuit is not sustainable. While new digital x-ray technology is cool and does provide “somewhat” better diagnostic imagery most pet’s needs can be met by current technology. The result is that the cost of these new technologies must be spread over the entire client base to pay for these expensive new pieces of equipment. Despite the non-sustainability of this business model I cannot see vet medicine deviating from this path  for the foreseeable future unless the current recession we are in permanently changes the way consumers shop for veterinary services. As I look at the professional journals I see countless numbers of one man practices up for sale. Many of these practices cannot keep pace with the proliferation of new technology in these “mega” hospitals and probably have finally throw in the towel instead of finding a niche in which they can compete. This is so sad but I can easily envision a time when the number of small 1-2 vet practices in urban American areas will be almost zero. The small local vet is being replaced by the large corporately owned or managed multi-vet hospital just off the interstate. As a practice owner I welcome corporate competitors as I know I can always provide better, less expensive and more compassionate service but I worry for new graduates. Too much corporate ownership will eventually limit their choices upon graduation and fewer options will always lead to lower wages in the long run. While the opposite is true now with respect to wages as corporate practices have difficulty with retention, I also believe that this is changing given our current economic situation.

I also believe that the increase cost of veterinary medicine that we are discussing is causing a crisis in our client base. Two groups of clients (generally) have emerged in the last ten to fifteen years. One, the client that is highly devoted to their pet or pets, and, with encouragement from the media and the veterinary profession over the years, requests and expects a quality of care approaching that of human medicine; i.e. cancer treatments, tertiary care such as C.A.T. scans and MRI’s, and specialized veterinary medicine that encourages referral to the profileration of specialists in medicine, surgery, opthalmology, oncology, etc. we see today. The second group, a larger and every expanding group, either value their pets but simply do not have the disposable income to spend much, if any, money on their care, OR, they continue to behave much like 20 years ago when the “value” of our pets was generally lower, so they were considered a more “disposable” asset. The veterinary profession really doesn’t want to talk about this group nor does it have any plan or strategy to deal with this group’s almost complete inability to obtain quality, affordable veterinary care for their pets. Instead, the profession focuses like a laser beam on the top 5-10% of the veterinary purchasing public and caters its prices, services, buildings, equipment and technology on that group and that group alone. This is NOT a sustainable strategy. We are squeezing out the average American that wants routine care such as vaccinations, sterilizations and  annual examinations at a price that the average household can afford. Recent data is showing us that while the feline pet population is increasing the frequency of visits to the veterinarian is dropping. I don’t know if this is a seminal moment in veterinary medicine, but I do know that it is a trend that should cause all veterinarians pause. We cannot turn our backs on the majority of Americans that now use our services but will soon be squeezed out because of increasing costs due to the relentless elevation of  standard of care. Veterinarians must not focus solely on the elite client and their demands with new fangled gadgets, technology and speciality equipment  while leaving the “average” client behind. As an industry we must stay grounded in reality, know who our clients are, and what level of care they demand. I’m NOT advocating a decrease in the standard of care, but I am advocating a baseline of care that most Americans can afford and then a holding of that standard for a period of time. If others, as we have now in the profession, practice a higher level of care then clients are free to seek more advanced procedures at those facilities and pay the commensurate higher price for those services. I contend, that we must work hard to preserve general practice and cultivate veterinarians with an expertise at the general practice level that makes providing veterinary medicine with a high standard still possible at a reasonable cost. We cannot continue to atrophy the scope of services the general practice provides by citing the “Standard of Care” doctrine and moving those procedures within the purview of the specialist. I believe this philosophy has already hurt general practices and continuation down this path can only hurt the general practitioner and their dwindling client base.

I welcome your comments and hope that both pet owners and veterinarians will join the discussion on this topic as it is certainly something that we as a industry must address within the next 10 years.

One last little bit of trivia. Percorten-V is a drug used in the treatment of Addison’s disease. It costs $122.70 for a 4ml vial; or $30.675 per ml; $14,509.275 per pint; $116,074.20 per gallon; or $4,875,116.40 per barrel (42 US Gallons). Yes almost $5 million dollars a barrel even more than a barrel of HP ink! Incredible don’t you think.

Ask The Vet: Euthanasia – When Will I Know Doc?

by petloverunplugged on October 22, 2009

Becky, the owner of a 15 year old domestic short hair cat, asks: “When will I now when it is time to say goodbye to my cat – what are the signs?”

When Will I Know Doc?

As veterinarians we dedicate our lives to saving the lives of our companion pets but there are some days when there is nothing more that we can do and we as pet owners and veterinarians must face the inevitable – humane euthanasia.  The difficulty is knowing “when” this times comes and it is a question we as veterinarians are asked frequently when clients come to visit us with old and very ill pets. It is a question that we as veterinarians cannot answer for our clients but it is an opportunity where we can provide much support and guidance. But before I take you through the “clinical” checklist all vets use to help their clients make this very difficult decision let me briefly tell how my husband and I dealt with this very situation a few years ago.

Shortly after arriving in Oregon in 1992 my husband and I welcomed the newest additional to our family (me, my husband and our Rotweiller ALF) an 8 week old Australian Shepherd name Sydney. She was the apple of daddy’s eye, they bonded quickly and formed a warm and trusting relationship that would lasted for over 13 years. When Sydney was only four we realized that she had juvenile cataracts that required very expensive surgery. Shortly thereafter we decided to forgo our own Christmas gifts and give her the gift of sight once again.  We took her to a veterinary opthalmologist to perform bilateral lens replacement in November of 1996. After eight long weeks with an elizabethan collar Sydney emerged with two new lens and much improved vision. Sydney went on to live a wonderful, happy and frisbee chasing life for the next 9 years. But then suddenly in 2005 her hearing started to faded as her eye sight finally betrayed her. It broke my husband heart to see her struggle in the house and then with diminishing hearing she started to withdraw from the world and the very close relationship they had together for over 13 years. While her “health” was fine her quality of life suddenly ceased to exist. She became frighten easily and was for the first time in her life weary of everyone but me and my husband. For Sydney, life was no longer a playful afternoon in the park chasing the frisbee but one filled with fear and uncertainty. When that day arrived we knew it was time but it was oh so difficult for my husband to let go. I performed the euthanasia as my husband held Sydney in his arms for the last time. It brings tears to my eyes now just remembering how wonderful a dog Sydney was and how distraught my husband was that day. So yes, as a veterinarian we deal with the death of our clients pets almost daily but we also deal with it ourselves on a personal basis so we too know the difficulties involved with euthanasia.

But what do I tell my clients when they ask, “How will I know when?”  The answer for me was quality of life for Sydney. Although her health was otherwise ok, her quality of life was almost none existent. WHile there is a “checklist” of questions we ask client the bottom line is truly quality of life. For my clients I tell them if their pet can no longer experience the things it once enjoyed (chasing the frisbee), cannot respond to them in its usual ways, or appears to be experiencing more pain than pleasure, more bad days than good days, then they may need to consider euthanasia. With terminally ill or critically  injured pets, as veterinarians we can evaluate a pet’s condition and provide a prognosis but only an owner can determine quality of life as they know their pet better than anyone -for me quality of life is the most critical factor in making this most difficult of decisions.

Plan Ahead

No one wants to think about euthanasia, but  thinking about it once our pets do get older is wise as most of us need to prepare emotionally for that day. Preparing probably won’t make the decision any easier but it probably will help make it a better one for both ourselves and our pet. We must work out in our our minds “when” the time will be right. Many clients ask me if their pet will give them a “sign” to let them know the time is right. That I cannot answer but what I do know is that it is in our pet’s nature to endure and to sustain the “norm” at all costs – show no weakness in the “wild.” Our pets are much tougher than us so we must assume that the discomfort we see is much less than the discomfort they are really feeling.

Our Pets Trust Us to Make the Right Decision

Our pets love us unconditionally, they are not emotionally selfish and the trust they have in us as pack leaders to make the right decisions on their behave is unwavering. They know our decision to finally let them rest is in their best interest. As pet owners we must understand that with ill or critically injured pets we are not artificially ending life but determining when to cease artificially extending life.  Trust me, I know this can be a gut wrenching decision but planning for that day will help both you and your pet make the right decision when the time comes. Our pets know that despite the fear and sadness that cripples us as we make this decision, in their brave hearts they know we will have the courage to make the right decision on their behalf when the time is right and lay them peacefully to rest.

I will leave with links to numerous other sites that will provide you with more information of pet euthanasia and this poem “The Rainbow Bridge” a poem that  brings tears to my eyes ever time I read it.

Rainbow Bridge 

Just this side of heaven is a place called Rainbow Bridge.

When an animal dies that has been especially close to someone here, that pet goes to Rainbow Bridge.
There are meadows and hills for all of our special friends so they can run and play together.
There is plenty of food, water and sunshine, and our friends are warm and comfortable.

All the animals who had been ill and old are restored to health and vigor; those who were hurt or maimed are made whole and strong again, just as we remember them in our dreams of days and times gone by.
The animals are happy and content, except for one small thing; they each miss someone very special to them, who had to be left behind.

They all run and play together, but the day comes when one suddenly stops and looks into the distance. His bright eyes are intent; His eager body quivers. Suddenly he begins to run from the group, flying over the green grass, his legs carrying him faster and faster.

You have been spotted, and when you and your special friend finally meet, you cling together in joyous reunion, never to be parted again. The happy kisses rain upon your face; your hands again caress the beloved head, and you look once more into the trusting eyes of your pet, so long gone from your life but never absent from your heart.

Then you cross Rainbow Bridge together….

EIC in Labrador Retrievers

by admin on October 17, 2009

Did you know that exercise-induced collapse (EIC) has become prevalent in pedigreed Labrador retrievers over the past couples of decades. EIC is a weakness in the rear limbs during strenuous exercise that can spread to the forelimbs. There is now a test for EIC and is available for $65 through the University of Minnesota Veterinary Diagnostic Laboratory.

Ask The Vet: Questions About Travel By Air

by petloverunplugged on October 16, 2009

Donna, from Seattle, Washington, asks: “I’m planning to visit my parents for Christmas back east and want to take my cat, what do I need to do?

As the holiday season approaches many pet owners are preparing to travel with their pet(s) and one of the commonly asked question is “What do I need to travel with my pet?” The answer depends on how and where you are traveling. In most cases if you are driving across state lines you should have a “health certificate” from your veterinarian but the reality is you never get checked so just make sure your pet has a current rabies vaccine and you have proof of that vaccine.

If you travel by air a health certificate is required buy all airlines and you may even need a letter of acclimation from your veterinarian although this seems very redundant more airlines are requiring it. Here are a few things you should know before you get your health certificate at your local veterinarian.
1.Your pet must be current on its rabies vaccines.
2. Your health certificate is valid for 30 days and your pet must be examined within 10 days of issuing a health certificate.
3. Check with your airline to see if they require a letter of acclimation from your veterinarian and also find out from the airline what they want in the letter. This is important because your veterinarian may NOT know what a specific airline may require as they are all different and often change their requirements regularly. So be proactive and find out before you get to your veterinarian as this could save you lots of time and hassle. Also note that some breeds are banned from summer time travel by some airlines i.e. bulldogs, etc. CHECK first.
4. If your pet travels as “cargo” the airlines also have specific rules about how large their crates must be, proper signage on the crate, etc. So find out before you get to the airport what crate size your pet needs, food & water dishes, signs on outside of kennel.
5. If you are traveling overseas with a pet it is essential that you find out well in advance about vaccine requirements, possible quarantine period, and the much more complex international health certificate requirements. Each country in the EU is different so you must contact them directly to get the most up to date requirements. Here is a link to a very helpful website that every pet owner should at least look at before planning to travel by air with a pet.
www.pettravel.com/passportnew.cfm
6. Know the exact address of where you are traveling as this information is required on your pet’s health certificate.

For more information on traveling with your pet and links to some airlines visit my hospital web site @ http://wvah.net and look in “other Places to Visit” and you will find a complete section on Help with Travel.

If you know of any great sites please let me know and I’ll include them.

Ask The Vet: My Dog/Cat is Vomiting – What Should I Do?

by petloverunplugged on October 15, 2009

Alicia from Portland, Oregon asks: My dog vomits every once in a while, when should I concerned about it and what should I do?

In my practice I probably get this question more than any other.  I will answer this question by referring to a dog but many of my comments also apply to cats. I typically answer the question by first asking some questions. The first is how frequently has your dog vomited? If the answer is just once or twice and your dog shows no other signs of distress, no fever or obvious abdominal pain, and is no more than slightly depressed (inactive), you can probably treat the vomiting at home.  Keep your dog off food for a while (if you feed twice daily skip the next meal) and make sure they have water available to drink. The reality is vomiting occurs commonly in dogs. It seems to be caused most often by irritation of the stomach, called simple gastritis. And the most common cause of gastritis are dietary related – your dog overate, you just changed your pet’s food (or your dog just got into the cat food bag) your pet has food allergies or got into the garbage or compose pile. The first two causes can usually be dealt with at home but the latter three will require a visit to your veterinarian to be successfully resolved.

Because of this I often start by asking the owner if they know if their dog has gotten into the garbage or some other toxin, if there is diarrhea associated with the vomiting or if there was bloody vomiting. Again if the answer is no I recommend they watch their dog carefully for the next 24 hours and if more vomiting occurs bring them in to see us.

But if their dog has vomited more than a few times, if the vomiting is extremely forceful, if there is blood in the vomit or if there is obvious abdominal pain, or if the dog seems particularly depressed or weak, has a fever, or retches unproductively their pet should be seen by a veterinarian as soon as possible. If this is the case and the pet comes in the owner should be prepared to answer a few more questions to help us determine what is wrong with their pet. Keen observation of your dog is very helpful in diagnosing any problem.

In this discussion it will impossible to diagnose what’s wrong with a pet but I can help you get a better understanding of what your dog is doing and whether or not it should be seen by your veterinarian. The first thing that must be determined (and its not always easy) is whether or not your pet is vomiting, the expulsion of food, fluid or debris from the stomach or small intestine, or regurgitating, the effortless ejection of contents of the esophagus. The big difference between the two is that regurgitation is effortless, while vomiting is an active process with strong abdominal contractions. By carefully observing your pet you may be able to tell the difference. When your pet regurgitates it usually lowers its head and food is expelled without effort and the regurgitation is usually undigested food, tubular in shape and is often covered with a slimy mucus. My dogs usually want to eat their own vomit when this happens. Vomiting, on the other hand, causes your pet to be apprehensive and heaves and retches to vomit.

If the owner determines that their pet is vomiting and takes them to the veterinarian here are a few of the things your veterinarian will do to determine what may be causing your pet’s vomiting.  First your veterinarian will attempt to determine if the vomiting is caused by gastric (primary) or non-gastric (secondary) diseases. With so many older dogs suffering from arthritis we always ask if owners are using over-the-counter medications such as aspirin or ibuprofen as even short term usage of these medications can cause severe stomach ulcers in dogs with even more serious consequences in cats. By determining primary or secondary gastric causes your veterinarian can then discuss with you the most likely causes for each condition. This is not an exhaustive list but simply the most probable list of causes.

The most common primary or gastric causes of vomiting are:

  • Gastritis
  • Stomach ulceration i.e. use of aspirin or ibuprofen
  • Stomach cancer
  • Obstruction i.e. foreign bodies such as socks; telescoping intestine
  • Hiatal hernia i.e. part of stomach herniating through the diaphragm – pet hit by car
  • Inflammatory bowle disease
  • Intestinal cancer
  • Worms

The most common secondary or non-gastric causes of vomiting are:

  • Pancreatitis i.e. infection or inflammation of pancreas
  • Kidney failure, either acute from poisons such as antifreeze or chronic failure
  • Pyometra i.e. infection of the uterus found in older non-spayed female pets
  • Liver failure
  • Hyperthyroidism in cats
  • Hormonal disease such as Addisons disease, Diabetes mellitus, Septicemia
  • Parvo in young unvaccinated dogs usually associated with bloody diarrhea
  • Panleukopenia virus in unvaccinated young cats

Please keep in mind that this discussion is not meant to be a substitute for veterinary care but an aid in helping you help your veterinarian determine what is causing your pet’s vomiting.  If you find this helpful please let me know and if you would like more information on any of the diseases listed above just ask and I will provide links to other sites and a brief discussion for your review.

Ask The Vet: Canine Influenza – H3N8 Virus

by petloverunplugged on October 14, 2009

Suzanne from Orlando, Florida, asks: Being from Florida I’ve heard lots of canine influenza, is it similar to H1N1 virus and can I get it from my dog?

At our practice we are constantly asked about canine influenza (CI), if there is a vaccine for it and if we can catch it from our dog.

Canine influenza is a flu virus, subtype H3N8, that causes respiratory infection in dogs. It appears to be an airborne disease, much like kennel cough (Bordetella bronchiseptica), and most importantly humans, cats and other animals CANNOT catch this flu virus from dogs. Physical contact between dogs does not seem to be required for transmission, but if your dog stays at home and rarely comes into contact with other dogs, its risks of contracting the virus is likely to be low. Dogs that are boarded, attend doggie day care or play in dog parks are at higher risk if the virus is circulating in the area.

Symptoms

The majority of infected dogs exhibit the mild form of CI. In the mild form, the most common clinical sign is a cough that persists for 10 to 21 days despite treatment with antibiotics and cough suppressants. Most dogs have a soft, moist cough, whereas others have a dry cough that is similar to that induced by Bordetella bronchiseptica parainfluenza virus infection. Many dogs have a purulent nasal discharge and a low-grade fever.

Transmission

Canine influenza is spread via aerosolized respiratory secretions and contaminated objects (kennel surfaces, food and water bowls, collars and leashes) and people moving between infected and uninfected dogs. The virus can remain viable (alive and able to infect) on surfaces for up to 48 hours, on clothing for 24 hours, and on hands for 12 hours. The incubation period is usually two to four days from exposure to onset of clinical signs. The highest amounts of viral shedding occur during this time; therefore, dogs are most contagious during this 2-4 day incubation period when they are not exhibiting signs of illness.  Virus shedding decreases dramatically during the first 4 days of illness but may continue up to 7 days in most dogs and up to 10 days in some dogs. Because this is a newly emerging pathogen, all dogs, regardless of breed or age, are susceptible to infection and have no naturally acquired or vaccine-induced immunity when first exposed to the virus. If the virus enters a kennel or other closed group, a high percentage of the dogs may become infected, and most of these dogs will be symptomatic. Approximately 20-25% of infected dogs are expected to remain asymptomatic, but can still shed the virus and spread the virus. Although most dogs have a milder form of canine influenza and recover without complications, some may develop severe pneumonia.

Prevention

A canine influenza vaccine is now on the market, it requires an initial dose and then a booster in two to four weeks and can be administered to dogs six weeks and older. The canine influenza vaccine is a “lifestyle” vaccine, and is not recommended for every dog. In general, the vaccine is intended for the protection of dogs at risk for exposure to the CI virus, which include those that either participate in activities with many other dogs or are housed in communal facilities, particularly where the virus is prevalent.
