Stop That Scratching!

April 22, 2010

If the sounds of a canine or feline “scratchfest” is interrupting your slumber, or you’re snarling, “Stop scratching!” several times a day, chances are you have an allergic pet on your hands. Just as with human hay fever, most dog and cat allergies are the result of an exaggerated immune system response to allergens in the environment such as plant pollens, tree pollens, and mold spores.  The scientific name for this inherited allergic condition is atopy or atopic dermatitis. Terriers of any type are notorious atopy sufferers along with Dalmatians, Lhasa Apsos, Shar-peis, Bulldogs, and Labrador Retrievers. 

Whereas people are prone to runny nose and eyes, dogs and cats with atopy develop itchy skin, often accompanied by skin and ear infections. Symptoms are initially mild and seasonal, but tend to progress year by year in terms of severity and duration.  Fortunately, there are many options for treating atopy including medicated shampoos, antihistamines, fatty acid supplements, and drugs that alter the immune system’s overzealous behavior (cyclosporine, cortisone).  Just as for people, desensitization injections can be administered after specific testing is done to determine which allergens are provoking the immune response. Elimination of exposure to the allergens may also be an option (a good excuse to move to Hawaii!). 

Some dogs and cats develop allergies to their food.  This can result in year round itchy skin, ear infections, and/or gastrointestinal symptoms (vomiting, diarrhea, gassiness).  If a food allergy is suspected, your veterinarian will recommend an “elimination food trial.”  This requires strict adherence (including elimination of your pet’s favorite treats) to feeding a novel protein diet for six to eight weeks. There are many such diets to choose from these days that contain duck, rabbit, venison, salmon, and even kangaroo! If the chronic symptoms disappear in response to the diet change, voila, the diagnosis of food allergy has been made. One must then hope that, over time, the animal doesn’t develop an allergy to the new diet! 

Lastly, some dogs and cats develop an allergy to fleas, more specifically, to the flea’s saliva.  Whereas many fleas are required to cause most animals to scratch like crazy, for those with a flea allergy, just one bite is all it takes to set off an intensely itchy reaction that can last for days. The best treatment for this allergy is stringent flea control, or relocation to Colorado; fleas don’t survive in high altitude locations! 

‘Tis the season for fleas and seasonal atopy.  Do you have an itchy dog or cat on your hands?  If so, what will your strategy be to soothe your pet’s itch and preserve your sanity? 

Best wishes to you and your four-legged family members for abundant good health,

Fish Oil (Omega-3 Fatty Acids): a Proven Treatment for Canine Arthritis

January 30, 2010

 I had the good fortune of receiving my veterinary school training at Cornell University.  Part of what made this education so fabulous was that the senior faculty spent a great deal of “face time” with their students.  I have fond memories of a seasoned clinician patiently holding a Dachshund for me while teaching this novice how to collect a blood sample from the jugular vein.  Another taught this city slicker how to collect a milk sample for mastitis testing from the teat of a cow.   A major “take home point” my classmates and I received from these icons in veterinary medicine was, “First, do no harm.”  In other words, before subjecting our patients to diagnostic testing or treatment, we should strive to be as confident as possible that the potential for benefit was far greater than the potential for harm.  “First do no harm” has always been my mantra and is the main reason I try to rely on “evidence based medicine” (facts substantiated by research) rather than anecdotal information to support what I do. 

Unfortunately, there is a paucity of evidence based medicine pertaining to the use of many commonly used supplements, nutraceuticals, and herbs for dogs and cats.  This is the reason a big smile appeared on my face when I opened a recent edition of the Journal of the American Veterinary Medical Association.  It contained two studies on the effects of omega-3 fatty acids (fish oil) for the treatment of osteoarthritis (also known as arthritis or degenerative joint disease) in dogs.  The study designs were excellent in that many dogs were included, there was a control group (some dogs received a placebo rather than the fatty acids), and the observers were “blinded”- neither the veterinarians nor the dogs’ families knew if the dogs were receiving the fatty acids or the placebo.  

Fish Oil (Omega-3 Fatty Acids)Here’s what the studies showed.  Compared to the placebo group, the dogs receiving omega-3 fatty acids had a significantly improved ability to rise from a resting position and play by six weeks after beginning supplementation, and improved ability to walk by 12 weeks.  Additionally, compared to the control group, dogs receiving the fish oil had improved weight bearing on the affected limbs as assessed by force-plate analysis (an extremely humane testing method).  No significant adverse side effects from the fish oil supplementation were reported. 

If you’ve spent any significant amount of time with dogs (especially large dogs), guaranteed you’ve known at least a few with arthritis.  It is estimated to affect up to twenty percent of dogs over one year of age. Dogs with arthritis resemble people with arthritis- they are often stiff and slow to rise when they first get up in the morning, as well as after vigorous exercise.  There are many ways to treat this common canine malady including nonsteroidal anti-inflammatory medications (the equivalent of ibuprofen for humans), acupuncture, rehabilitation therapy, and supplements that increase the production of normal joint fluid.  The effectiveness of all of these modalities, including fish oil, will vary from individual to individual.  The beauty of fish oil is that, likely the only potential significant risk is for you- your dog may develop fish breath! 

I love the fact that veterinarians now have evidence based support for recommending fish oil as a treatment for their canine patients with arthritis, and in doing so, they can abide by the mantra of, “First do no harm.”  If you suspect your dog has arthritis (if you have a large breed dog over eight years of age, chances are that you do), talk with your veterinarian about the pros and cons of all the treatment options.  And the next time you are dining on fish, don’t be surprised if your dog’s nose appears right beside your dinner plate.  Chances are, your dog clearly recognizes the benefits of fish oil supplementation!  Now, pass the salmon please. 

Wishing you and your four-legged family members abundant good health.
