Most Common Canine Allergies

Signs of canine allergies include itching, coughing or other respiratory problems or gastrointestinal problems such as diarrhea or vomiting. Allergies in dogs have several common causes. If you suspect that your dog is suffering from allergies, finding the underlying cause is a crucial step in treating the condition and alleviating the symptoms.

  1. Airborne Allergies

    • The single most common allergy found in dogs is airborne/inhalant allergies. The same airborne allergens that affect humans affect dogs --- including pollens, mold, dust mites and mildew. Inhalant allergies may occur seasonally, but some allergens (such as dust mites, mold or mildew) are present regardless of the season. Severe itching over the entire body is the most common symptom of an inhalant allergy. Treatment options include anti-inflammatory therapy, shampoo therapy and the most costly option --- hyposensitization (allergy shots).

    Flea Allergy

    • Flea allergies are a common canine health problem. A flea has more than 15 potential irritants in its saliva; the allergic reaction commonly occurs in the area of the flea bite. Symptoms may include severe itching, chewing, thinning hair/hair loss, skin inflammation, hot spots, open sores and scabs. Dogs with flea allergies frequently exhibit symptoms near the base of the tail and rump area. The first step of treating the allergy is removing the dog from fleas by implementing flea control measures --- such as flea shampoo or topical medications. Additional measures will be necessary to treat your home and any surfaces that the dog comes into contact with. Your veterinarian may prescribe a course of antibiotics if your dog is suffering from a skin infection.

    Food Allergies

    • Food allergies commonly emerge after a dog has eaten a specific food for an extended period of time. According to Aztec Animal Clinic, food allergies in dogs most likely develop as a response to the proteins found in the food. Common culprits include beef, chicken, pork and turkey. Symptoms include itching, respiratory problems such as wheezing or coughing and vomiting or diarrhea. If the symptoms last several months, your vet may introduce a hypoallergenic diet for a period of eight to 12 weeks as part of an allergy test.

    Bacterial Allergy

    • Staphylococcus is commonly found on dog skin and, under normal conditions, does not cause any irritation. Dogs with a bacterial allergy exhibit symptoms similar to a staph infection. Lesions ranging from 1/2 to 2 inches in diameter appear, along with hair loss that looks similar to ringworm. Your veterinarian will prescribe antibiotic therapy to control your dog's reaction.
