Treatment of Allergies in Pets
Treatment of Allergies in Pets
Spring officially arrived nearly three weeks ago, but the onset of allergy season may not arrive too soon this year, given our harsh winter. But once it warms up, pollen, dust mites, fleas, grass, weeds and mold will kick off allergy season in pets.
Clinical Signs of Allergies
Does your dog rub his face along the front of your sofa or scratch incessantly? Has your cat scratched all the fur off her head and made is scabby? Are you constantly putting in ear drops or giving antibiotics to treat skin infections? All these represent clinical signs of allergies in pets.
One of the top causes of canine and feline allergic skin disease stems from an allergic reaction to flea saliva. A flea bites your dog or cat, setting off an allergic reaction. This disease presents a double-whammy to your pet: discomfort from fleas crawling all over its skin and the discomfort of being itchy. Fortunately, numerous options for control of fleas are available and your choice of product can be tailored to your pet’s exact needs.
Modify the Diet
Food allergies are typically an ongoing problem, not seasonal like pollen, grass or flea saliva allergies. Veterinarians think the allergen in food is the protein source contained in the diet, but it may be other ingredients as well. The standard method for determining if food is the cause of skin disease is a food elimination trial. Elimination diets contain a limited number of ingredients and protein sources not typically found in common pet food and not previously fed to your pet. Novel protein sources include bison, herring or rabbit. Some elimination diets avoid common carbohydrate sources and include potatoes or oats, rather than corn or soy. An elimination diet requires determination on the part of the pet owner, as the skin improves slowly in response to a diet change. Patience is required to tough out a month or more of strict diet control.
Immunotherapy, a medical word for allergy shots, involves specialized testing to determine whether it is pollen, dust mites, fleas, grass, weeds or mold revving up your pet’s itch-scratch pathway. Once the cause of the allergy is determined, a custom allergy vaccine can be developed for your pet. You learn to give the injections at home one to two times per week. These injections contain minute amounts of the offending antigen (pollen, dust mites, fleas, grass, weeds or mold) which trains your pet’s immune system to be tolerant of these agents.
Quell the Immune System with Drugs
A variety of drugs can be used to turn off the allergic reaction underlying the itch-scratch cycle in your pet. The most well-known, but not necessarily the most effective in pets, is antihistamines. Steroids can be very effective and rapidly reduce the clinical signs of allergies, but have unpleasant side effects, such as increasing water drinking, urination and appetite, as well as increasing the risk of infection. Another effective drug for allergy management is cyclosporine, although cost is a concern. New to the market, oclacitinib, inhibits the cells initiating the itch-scratch cycle by attacking allergies at the cellular level.
With so many options to manage pet allergies, no pet should have their summer fun spoiled by constant itching and scratching. Watch The AMC’s Dr. Mark Macina talk about managing allergies in pets.
