Dog Eye Allergy Symptoms

Dog eye allergy symptoms may be triggered by a wide range of factors, most commonly inhaled substances from the environment. The culprit allergens will affect the immune system and will result in a number of symptoms, which will also affect the dog's eyes and the eye area. Recognizing the symptoms of eye allergies can be helpful so that you can relieve the dog's discomfort faster.

Inflammation of the Conjunctiva

The conjunctiva is the white visible area in the dog's eyes. When the dog is allergic, the conjunctiva will become red and inflamed. This is caused by the presence of inflammatory cells, known as histamines, which are produced by the immune system. The immune system produces these inflammatory cells when in contact with the allergen substances. The inflammation of the conjunctiva is also known as conjunctivitis, and may be caused by several other medical conditions besides allergies.

Frequent Dog Eye Discharges

The second most common symptom of dog eye allergy after the inflammation of conjunctiva is the presence of watery discharges from the dog's eyes. The discharges may be periodical and will be more visible after the dog has been exposed to the allergen. The discharges may often be accompanied by sneezing in cascades.

Excessive Tearing

In addition to the eye discharges, the dog may also present excessive tearing.

Eye Squinting

You may notice your dog is squinting periodically. This may be due to the pain or discomfort caused by the conjunctivitis.

Pawing of the Eyes or Face

The inflammation of the eyes can cause pain and the dog may show this by pawing the facial area. You will see him covering his eyes or his face with his paws, or burying his face in soft or cold surfaces such as his bedding.

Scratching the Face

The allergens can cause itchiness and the dog may scratch his face and even the eye area. If the dog scratches intensively, this may lead to hair loss or even serious wounds.

Secondary Infections and Dog Eye Allergies

Secondary infections may accompany the rest of the dog eye allergy symptoms. The bacteria, fungi or viruses can attack the dog's eyes, which are more exposed to infections. The dog may also infect his eyes with his paws, which carry a lot of bacteria, viruses or fungi from the environment. The infections can cause additional symptoms such as more consistent, colored discharges (may be yellow, brown or pink, depending on the causing agent of the infection). Pus may also be secreted if the infection is advanced and not treated. The secondary eye infections can be so severe that they cause the eyes to completely shut.

It is critical to identify the allergen and reduce this from the dog's surroundings. Until finding the allergen, you should get some topical solutions and eye drops containing corticosteroids that can soothe the inflammation and relieve pain. Secondary infections may require oral antibiotics.
