Eliminating allergens from the environment is the best way to relieve allergies, states WebMD. Since this is not always possible, medication, bathing with an appropriate shampoo, supplements and adequate flea control also contribute to allergy relief.
Dogs experience allergies from allergens in the environment, ingredients in their food or medications and from sensitivity to flea bites, reports WebMD. Allergies in dogs cause similar signs to allergies in humans. Skin reactions include redness, hives, eye irritation, itchiness and scabbing. Inhalation of an allergen such as pollen or mold causes coughing, sneezing and snoring.
Medications such as steroids, antihistamines and medicated shampoos are effective against controlling the symptoms of allergies, explains WebMD. Omega-3 fatty acid supplements also work to reduce the itchiness of skin. If allergies are severe, allergy shots are available for some of the more common allergens. Dogs with flea allergies require year-round flea prevention on top of routine medications to reduce recurring flare-ups.
Plain over-the-counter Benadryl, with diphenhydramine as the only active ingredient, is safe to give to some pets instead of prescription medication, notes Veterinary Place. This is typically administered at a dose of 1 milligram per pound every eight hours. Dogs with glaucoma, heart disease, prostate disease and hyperthyroidism should not receive diphenhydramine. Always check with a vet before administering medication to a dog to prevent adverse reactions.
In cases where food ingredients are the cause of discomfort, try a prescription hypoallergenic diet, suggests WebMD. Feeding nothing but a hypoallergenic for 12 weeks assists in eliminating the skin problems associated with food-related allergies. Once signs have cleared, reintroduce regular foods and treats one at a time to help identify problem foods.
