Yes, dogs can be allergic to cats. Dogs may develop allergies to proteins found in cat dander, saliva, or urine, similar to how humans can be allergic to cat allergens. The exact cause of cat allergies in dogs is not fully clear, but it is believed that the same cat allergen Fel d 1, which affects humans, might also affect dogs. Symptoms of cat allergies in dogs often include itching, scratching or biting their skin, red or inflamed skin, sneezing, watery eyes, coughing, wheezing, and sometimes gastrointestinal issues. Some areas more exposed to allergens like paws and abdomen may be particularly itchy. Diagnosis typically involves veterinary evaluation including history, observation, ruling out other causes, and possibly allergy testing. Treatment can include managing exposure, frequent grooming and cleaning, and in some cases immunotherapy tailored to the dog's specific allergens. Despite allergies, it is possible for dogs and cats to live together with proper management of symptoms and environment to reduce allergens. This condition, while possible, is relatively less common than other allergies in dogs but is recognized by veterinarians and pet health professionals.
