Symptoms of Pet Allergies

Pets with allergies may experience a variety of symptoms, including:

Hot Spots

These are itchy, raw, or bald patches of skin that can be painful and may bleed. Hot spots are often caused by excessive licking or scratching.


Hives are raised, itchy welts that can appear on the skin. They may be caused by an allergic reaction to a vaccine, medication, food, or insect bite.


Pets with allergies may sneeze more than usual. This is often a sign of an allergic reaction to pollen, dust, or mold.

Vomiting and Diarrhea

Pets with allergies may vomit or have diarrhea more than usual. This can be a sign of an allergy to food or medication.

Causes of Pet Allergies

There are many potential causes of pet allergies, including:

Dust Mites

Dust mites are tiny creatures that live in dust. Pets with allergies to dust mites may have itchiness, sneezing, and runny eyes.


Pollen is a fine powder that is released into the air by plants. Some pets are allergic to pollen from certain trees, flowers, or grasses.


Mold is a type of fungus that grows in moist areas. Pets with mold allergies may have a runny nose, sneezing, and watery eyes.


Some pets are allergic to certain ingredients in their food, such as corn, soy, wheat, or beef. These allergies can cause vomiting, diarrhea, and itchiness.


Some pets are allergic to the ingredients in their medications, such as antibiotics or flea and tick products. These allergies can cause vomiting, diarrhea, and hives.

Shampoo and Grooming Products

Grooming products, such as shampoo, conditioner, and spray, can cause allergies in some pets. They affect the skin and coat, causing itchiness and hair loss.

Treatment for Pet Allergies

There is no cure for pet allergies, but there are ways to manage them. The best way to treat your pet's allergies is to avoid the things that trigger them. You need to be aware of the potential allergens and take steps to avoid them.

For example, if your pet is allergic to dust mites, you should keep their bedding clean and free of dust. If they're allergic to pollen, you should avoid taking them for walks during peak pollen times.
