Pets can become allergic to many things. Pollen (grass & trees) is a common finding as well as dust mites, and fleas. 10% of all allergens pets are allergic to are beef, chicken, and pork. Wheat and dairy products are also sources of allergies.
Allergy testing is done by a blood test. We test for 60 allergens. Once you know what the offending agents are, a decision has to be made. You cannot put the pet in a bubble. If found to be allergic to 10 or less allergens, immunotherapy can be started. Allergy injections can be administered or an oral solutions can be given. Over time, this will desensitize the pet to the allergens and decrease the itch. We have found that high allergy pets have more than 10 allergies and do not respond well to treatment and require additional medications.
Testing for food allergy is not accurate, so a prescription allergy food is feed for 6 weeks. Allergens are stored in the liver and need to be eliminated. If the symptoms are better after 6 weeks on the food, then a permanent diet change is made.
Allergy cannot be cured, but symptoms can be contained with the right combination of treatment, food and lifestyle changes. Quality of life will return.
