What are Dog Eye Allergies?

Dog Eye Allergies: Causes, Symptoms, and Remedies

Dog eye allergies are allergies that affect a dog’s eyes. The medical term for dog eye allergies is allergic conjunctivitis. In other terms, allergic conjunctivitis is inflammation and irritation of the eyes caused by environmental allergens.

Allergic conjunctivitis, which involves redness, irritation, and discharge of the eyes, can flare up during different seasons, or it can be present year-round.

While allergies in dogs commonly affect the gastrointestinal tract and skin, eye problems are possible.  In fact, dogs with allergic dermatitis, or inflammation of the skin from allergies, often suffer from allergic conjunctivitis.

Allergies that affect the skin and eyes are caused by a hypersensitivity to environmental substances, and this is often referred to as atopic dermatitis. While any breed or mixed breed can develop atopic dermatitis and subsequent allergic conjunctivitis, certain dog breeds more commonly have this condition.

These breeds are Golden Retrievers, Labrador Retrievers, German Shepherds, Bulldogs, Boxers, Cocker Spaniels, Doodle-type breeds, and Westies.

What Do Dog Eye Allergies Look Like?

A dog with allergic conjunctivitis may have eyes that appear very red, swollen, and watery. The watery appearance is caused by excessive tear production and can give the eyes a glassy appearance.

In more chronic situations, watery tears can progress to a thicker eye discharge which may be lighter in color.

The overall inflammation from dog eye allergies often triggers itchiness, and the dog may rub their eyes with their paws or along surfaces such as furniture.

What Causes Dog Eye Allergies?

Dog eye allergies occur as a result of allergic reactions on the surface of the eyes. Some of the most common environmental factors causing eye allergies in dogs include:

  • Tree and Grass Pollen: Eye allergy symptoms in dogs are often caused by pollen. Pollen can stimulate the immune system and trigger allergic reactions.
  • Mold and Mildew: These can not only lead to an allergic reaction and eye problems but also cause breathing difficulty in some cases.
  • Dust and Dust Mites: Dust and dust mites can cause sneezing and eye discharge. They can also trigger breathing difficulties.
  • Fleas: Fleas cause allergies which can lead to eye problems. Dogs suffer from a specific type of flea allergy dermatitis (FAD) – a sensitivity to flea saliva.
  • Dander, Hair, and Feathers: Pet and human dander and hair, as well as feathers, are potential allergens for dogs.
  • Cigarette Smoke: If dog owners smoke, it can lead to itchy eyes for your dog. That can then become an allergic reaction as it causes irritation to your dog’s cornea.
  • Colognes and Perfumes: Intensely scented chemicals, such as colognes, perfumes, and some household cleaners, are among the most common causes of allergic reactions.

Dog Eye Allergies: Causes, Symptoms, and Remedies

Eye redness, discharge, and itchiness are the most common symptoms of dog eye allergies. Here is a more detailed overview of the signs and symptoms of allergic conjunctivitis.

  • Eye Irritation: Red eyes are the first sign of eye allergies. Over time, the dog’s eyes appear swollen and sore.
  • Excessive Tearing: Excessive watery or mucousy eye discharge.
  • Squinting: If your dog has an eye allergy, you might notice them squinting.
  • Pawing: A dog with eye allergies will paw at its eyes or rub them along surfaces. This is the dog’s attempt to get rid of the allergen and relieve the itch.

How are Dog Eye Allergies Diagnosed?

To diagnose dog eye allergies, a veterinarian will perform a full physical examination, including the eyes. The veterinarian will rule out other causes of eye irritation, such as dry eye (known as KCS), corneal ulcers, eyelid growths, and infections, before diagnosing allergic conjunctivitis. Dog eye allergies are often diagnosed by ruling out other eye problems.

Vets may perform a test called  “conjunctival cytology“ – the veterinarian will swab the eye and analyze the sample under a microscope. The presence of inflammatory cells helps to confirm the allergy diagnosis in some cases, but this test may not be conclusive.

If your dog is not responding to your regular veterinarian’s treatment, they may refer you to a board-certified veterinary ophthalmologist or dermatologist for further evaluation. A veterinary dermatologist may recommend allergy testing to determine the exact allergen or allergens.

Does My Dog Have Allergies or an Eye Infection?

Dog eye allergies manifest with red and watery eyes, while eye infections result in more intense signs and symptoms, including light sensitivity and yellow or green purulent dog eye discharge, which may affect one or both eyes.

Untreated allergic conjunctivitis can evolve into eye infection, especially if the constant rubbing of the eyes results in bacterial contamination.

It is important to have your veterinarian examine your dog to differentiate the diagnosis of allergic conjunctivitis. Dr. Lisa Steinberg says, â€śWhen your dog’s eyes look red or irritated, your veterinarian may diagnose conjunctivitis from allergies after ruling out an infection, eyelid growths, dry eye, ulcers, glaucoma, and some autoimmune conditions.

Conjunctivitis from allergies, also known as dog eye allergies, is a condition I see almost every day in practice, and it tends to be more common during different seasons of the year. Once dog eye allergies are diagnosed, you can decrease your dog’s discomfort by keeping their eyes clean and rinsing them regularly as directed by your veterinarian.”

What Is the Treatment for Dog Eye Allergies?

Dog Eye Allergies: Causes, Symptoms, and Remedies

From home remedies to over-the-counter products to prescription medication – there are several dog eye allergy treatment options. Here are some popular treatments:

  • Saline Flushes: If your dog has a mild allergic reaction, you can simply flush the eyes with a gentle saline solution. This is not a cure, but it may help remove the allergen.
  • Eye Washes: Instead of saline, pet owners can use eye wash for dogs. Some of these eye wash solutions may be medicated, and some may help to simply flush the allergens from the eyes.
  • Eye Drops: Another treatment option are eye drops. Eye drops for dogs come with different active ingredients and often contain antibiotics and steroids or anti-inflammatories.
  • Antihistamines: These medications block the effect of histamine (the culprit behind allergies). The most commonly used antihistamine is Diphenhydramine (Benadryl).

It is very important to consult with your vet before treating your dog with any over-the-counter remedies
