What is hives in pets?
Hives, also known as welts or wheals, are an allergic reaction that causes red, raised bumps to appear on your pet’s skin. These lesions are usually very itchy and can appear anywhere on the body.
Causes of hives in pets vary and may include:
Food allergies: Reactions to certain ingredients in food, such as chicken, wheat, or soy, are a common cause.
Insect bites: Flea, mosquito, or bee stings can trigger an allergic reaction.
Contact with irritants: Exposure to chemicals, toxic plants, or detergents can cause hives.
Infections: Some bacterial or parasitic infections may lead to hives.
Medications: Certain medications can cause allergic reactions in some pets.

Treatment for hives will depend on the underlying cause. Your veterinarian may recommend:
Medications: Antihistamines to relieve itching, corticosteroids to reduce inflammation, and other medications as needed.
Therapeutic baths: Baths with special shampoos to soothe itching and reduce inflammation.
Special diet: If the cause is a food allergy, an elimination diet may be recommended to identify the allergen.
Infection treatment: If hives are caused by an infection, appropriate medications will be administered.
When to see a veterinarian:
If you notice signs of hives in your pet, it’s important to take them to the veterinarian as soon as possible. The veterinarian will perform a physical exam and may recommend additional tests to determine the cause and the most appropriate treatment.
