Discovering that your dog has hives can be alarming. These raised, itchy welts can appear suddenly and often mean that they are having an allergic reaction. Fortunately, hives in dogs are typically manageable with the right care. In this article, we’ll explore the causes, symptoms, and treatment options for dog hives so you can help your pup feel better quickly.
What Are Hives in Dogs?
Hives, also known as urticaria, are localized patches of swelling on a dog’s skin. They can appear as small, round bumps or larger, irregularly shaped welts. Hives are sometimes accompanied by redness, itching, and sometimes swelling around the eyes and muzzle.
Causes of Hives in Dogs
Hives are usually the result of an allergic reaction. Common triggers include:
- Insect bites or stings (e.g., bees, ants, or spiders)
- Certain foods (new treats or table scraps)
- Environmental allergens (pollen, mold, or grass)
- Medications (antibiotics, vaccines, or other drugs)
- Contact irritants (shampoos, cleaning products, or plants)
- Stress or anxiety
Identifying the trigger can help prevent future episodes of hives, so it’s really important to take note of any new exposures your dog has experienced.
Symptoms of Hives in Dogs
The most common symptoms of hives in dogs include:
- Raised, round, or irregular bumps on the skin
- Redness or inflammation
- Intense itching or scratching
- Swelling around the eyes, lips, or other areas
- Skin sensitivity or tenderness
In severe cases, dogs may also experience difficulty breathing, which requires immediate veterinary attention.
What Is The Treatment For Dog Hives?
Treating hives in dogs focuses on addressing the underlying cause and providing relief from itching and swelling. Here are the most common treatment approaches:
Over-the-Counter Antihistamines
Antihistamines like diphenhydramine (Benadryl) can help reduce swelling and itching caused by hives. Always consult your veterinarian before giving your dog any medication to ensure the correct dosage and safety.
The oral dose for Benadryl in dogs is 1mg per pound. So the dose for a 25lb dog would be 25mg of Benadryl.
Steroids
In more severe cases, your veterinarian may prescribe corticosteroids to control inflammation and itching. These medications should only be used under professional guidance.
Cold Compresses
Applying a cold compress to the affected areas can soothe itching and reduce swelling. Use a clean, damp cloth and gently hold it against your dog’s skin for 10-15 minutes.
Bathing Your Dog
If the hives are caused by a contact allergen, giving your dog a bath with a gentle, hypoallergenic shampoo can help remove the irritant and calm their skin
When to See a Veterinarian
While mild cases of hives often resolve on their own or with simple treatments, you should contact your veterinarian if:
- The hives worsen or spread
- Your dog shows signs of difficulty breathing
- Swelling occurs around the throat or muzzle
- The hives persist for more than 24 hours
As a veterinarian, I have treated several dogs with hives. My typical treatment is simply two injections – Benadryl and a steroid called Dexamethasone SP. I will have my patient wait in the lobby or exam room for approximately 15 minutes to make sure some of the hives (or facial swelling) have gone down, and they get discharged home.
Preventing Hives in Dogs
To reduce the likelihood of hives in the future, consider my advice.
Keep a record of your dog’s activities, diet, and environment to pinpoint potential allergens. Opt for hypoallergenic shampoos and cleaning agents designed for pets. When trying new foods, treats, or medications, monitor your dog closely for any adverse reactions. Use vet-approved flea and tick preventatives to minimize the risk of insect bites.
Wrapping Up – Dog Hives Treatment
Hives in dogs can be uncomfortable, but with the right treatment, most cases resolve quickly. If your dog develops hives, act promptly to alleviate their discomfort and consult your veterinarian if needed. By staying vigilant and taking preventive measures, you can help keep your pup happy, healthy, and hive-free.
