Dog Allergies : 5 Main Types

Dog Allergies: Types and Treatments

Dogs, just like people, can have allergies. Spotting the signs early is essential so your dog can stay happy and healthy. Dogs usually have three kinds of allergies: skin, food, and environmental. Sometimes, the symptoms look the same, but knowing what to look for helps you find the proper treatment. This guide will explain each type, what causes them, and how to help your dog feel better.

What is an Allergy?

An allergy is when the body’s immune system reacts too strongly to something harmless. For dogs, things like Pollen, dust, specific foods, or flea bites can trigger an allergic response. This reaction happens because the body thinks these harmless things are dangerous. As a result, the dog might itch, sneeze, have an upset stomach, or show other symptoms. By finding out what’s causing the allergy, you can choose the proper treatment to help your dog feel better.

Can Dogs Have Allergies?

Can dogs have allergies? Yes, they can! Dogs can be allergic to pollen, mould, dust mites, certain foods, flea bites, or even ingredients in their grooming products. Many dogs deal with allergies, and it’s important to know what triggers them so you can help your pet feel better.

Types of Allergies:

Dogs can have different types of allergies. Here’s a simple explanation:

  1. Environmental Allergies: These come from pollen, mold, and dust. Dogs may itch or sneeze more during certain times of the year because of these.
  2. Food Allergies: Dogs sometimes react to foods like beef, chicken, or wheat. This can upset their stomachs or make their skin itchy.
  3. Flea Allergy Dermatitis: This condition occurs when a dog is allergic to flea bites. Even one bite can make a dog very itchy and the skin red.
  4. Skin Allergies: Pollen and dust can also cause a dog to scratch. This can cause red skin, loss of hair, and skin infections.
  5. Contact Allergies: If a dog’s skin touches certain materials, like some fabrics or cleaning products, it can get itchy and irritated.

Knowing what is causing the allergy is essential to help your dog feel better. Each type of allergy needs different care.

Types of Allergic Reactions in Dogs

  1. Allergic Dermatitis: The most common type of allergy that affects the skin. It is caused by:

     – Fleas: Some dogs are allergic to flea bites and saliva, making their skin red and itchy. Flea medication can help.

     – Food Allergies: Specific foods like chicken or dairy can make dogs’ ears or paws itchy.

     – Environmental Allergies: Dust, pollen, or mould can cause itching, mainly on the paws and ears.

  1. Urticaria (Hives): Itchy bumps on the skin that appear 6 to 24 hours after touching allergens. They aren’t dangerous but need antihistamine treatment from a vet.
  1. Edema of the Face or Throat: Swelling in the face or throat looks serious but usually isn’t deadly. It can be treated with an antihistamine injection and goes away in a day or two.
  1. Anaphylactic Shock: A severe allergic reaction that can be fatal if not treated quickly. It happens after things like bee stings or vaccines and causes a quick drop in blood pressure. If your dog has had this before, your vet can help you prepare for future problems.

Understanding the Dog Allergy Test: A Simple Guide

A dog allergy test is a simple and effective way to determine if you’re allergic to dogs. Here’s how it works:

1. Visit an Allergist: Schedule an appointment with an allergy specialist.
2. Skin Prick Test: The doctor will place a small amount of dog allergen on your skin, usually on your forearm or back, and lightly prick the area. If you’re allergic, you’ll develop a small red bump at the site within 15-20 minutes.
3. Blood Test: Alternatively, a blood test (specific IgE test) can measure your immune system’s response to dog allergens. This test is useful if you have a skin condition or can’t stop taking certain medications.

By taking a dog allergy test, you can better understand your allergies and find ways to manage your symptoms effectively.


In short, dogs can have different types of allergies, like those affecting their skin, food, or things around them. These allergies can make dogs itch, sneeze, or have stomach problems. It’s essential to know the type of allergy your dog has so you can treat it the right way. Vets can give medicine and allergy shots or suggest changes in food and lifestyle to help. Keep your dog away from things that cause allergies, like pollen, fleas, or certain foods, and see a vet if they show symptoms. With proper care and treatment, your dog can stay happy and healthy.
