Allergies are one of the most common reasons pet owners visit the veterinarian. Understanding the types, symptoms, and treatments is essential for every pet parent.

1. Types of Pet Allergies

Environmental allergies are triggered by pollen, mold, and dust mites. Food allergies typically involve proteins like chicken, beef, or dairy. Flea allergy dermatitis is caused by flea saliva.

2. Recognizing Symptoms

Common signs include excessive scratching, licking paws, recurrent ear infections, hair loss, and hot spots. In cats, allergies cause miliary dermatitis with small crusty bumps along the back.

3. Treatment Options

For environmental allergies, immunotherapy shots can desensitize your pet. Medications like Apoquel and Cytopoint provide relief. For food allergies, strict avoidance of the offending ingredient is the only solution.
