Hives can be scary. It’s like your dog is having a severe allergic reaction. But the good news is that most of the time, hives are harmless. So why do dogs get hives? What causes dogs to have hives?

It’s normal for dogs to have hives, but it can be scary if you’re not sure what is causing the reaction. We’ll go over the most common causes of hives in dogs and how to help your dog feel better.

What Causes Hives?

Hives are a reaction from the immune system that causes small red bumps or welts on your dog’s skin. These bumps are swollen blood vessels and are caused by histamine release during an allergic reaction. These reactions can be triggered by environmental factors like pollen, dust mites, or insect bites, as well as food allergies.

How Can I Help My Dog Feel Better?

If your dog is having a hive reaction due to an allergy, there are some things you can do to help them feel better:

  • Find out if they’re allergic to something in their diet by changing their diet or adding an elimination diet.
  • Make sure they always have access to water so they don’t dehydrate while they’re reacting.
  • Give them Benadryl before any kind of trip where they may be exposed to allergens (like a walk in the park).

What Causes Dogs to Have Hives?

Many things can cause dogs to have hives, including allergies, insect bites, stress, and even sunburn.

Allergies are a common cause of hives in dogs. If your dog has been exposed to something new that they are allergic to, they may begin to scratch or chew themselves excessively. If you notice any skin problems like this after your dog has been exposed to something new, take him/her to the vet immediately.

Insect bites can also cause hives in dogs. If your dog is bitten by a bug such as a flea or a mosquito, he/she may experience redness on the skin where he/she was bitten. This redness is typically accompanied by itching and scratching from your dog trying to relieve the irritation from the bite.

Stress is another common cause of hives in dogs. A stressful situation can include something as simple as having too many people around at once or being left alone for long periods every day without someone coming home every few hours or so just to check on them – these situations can cause stress for any animal!
