Affects: Dogs
Dogs are susceptible to allergies much like their human companions. Most allergies occur in dogs over 6 months old. A dog that is repeatedly exposed to a particular allergen becomes sensitized to it, and the immune system overreacts to a subsequent exposure, most commonly manifesting in the form of skin irritation. Some of the signs are redness, itching, hair loss, and recurring skin infections from the irritation. The dog may be more prone to scratching and licking at the irritated site, further exacerbating the problem.
Other common signs of allergies include coughing, sneezing, wheezing, ocular and nasal discharge, vomiting, diarrhea, and licking of the paws.
While it may be possible to identify the cause of an allergic response, it is best to seek attention from a veterinarian to identify the best treatment possible. To identify the specific allergens to which the dog is sensitive, veterinarians will commonly use a serum allergy test or a skin allergy test. Veterinarians may recommend either over the counter Benadryl without added decongestant or Zyrtec to alleviate clinical signs. If the allergy is more severe, allergy immunotherapy may be recommended.
