What Causes Hives in Horses?

Hives are a common skin problem in horses, but there is no one definitive cause. Some possible causes include environmental factors, food allergies, parasites, disorders of the immune system, and skin tumors. Hives can be mild or severe and can persist for days or weeks. Treatment typically involves avoiding the triggering factor and treating the underlying disorder.

Hives are a common skin reaction in horses, caused by a variety of factors. Most often, hives are the result of an allergic response, but they can also be caused by other factors such as stress, exposure to certain chemicals, or viral infections. Hives typically appear on the skin and may form into large, itchy bumps. Treatment typically involves relieving the symptoms with topical medications or injections, and sometimes the horse must be hospitalized for treatment.

What Causes Hives in Horses?

Hives in horses can be caused by many different things, but the most common are viruses. However, other things like food allergies, parasites, and environmental factors can also cause them. If you think your horse may have hives, it is best to take them to a vet for an evaluation.

Horse owners are always on the lookout for signs of illness in their horses, and one of the most common complaints is hives. It can be difficult to diagnose, but there are some common causes that may lead to hives in horses.

Here are the foremost common causes: 

1. Allergies:

Horses are often allergic to a variety of things, including grasses, trees, dust mites, animal dander, and other plants. If you suspect your horse has an allergy, it’s important to find out what triggers the reaction and avoid exposing them to those things.

2. Parasites:

One common parasite that can cause hives in horses is nematodes. These tiny worms live in the gut and can migrate into the skin when they’re infected with a worm disease or another condition.

3. Dermatitis Pruritus (DP):

This a chronic skin condition that occurs when the horse’s immune system reacts excessively to allergens. To diagnose DP, a veterinarian will first perform a skin scraping test to identify the allergen. If the allergen is not found on the skin scrapings, other diagnostic procedures such as blood tests or immunohistochemistry can be used.
