If the pet owner finds that there are a lot of eye booze in his dog's eyes, or the dog often sheds tears, it is likely that the dog has eye disease. Next, I will tell you about eye diseases in dogs.

1. Allergies: Dogs may experience allergic reactions after inhaling pollen, dust and other substances. These allergic reactions also include itchy eyes, eye booze flow, and redness in the skin around the eyes.

2. Conjunctivitis: If the dog's eyes are red and swollen, it is likely that it is suffering from conjunctivitis. These red and swollen areas will appear on the white parts of the dog's eyes, usually on the inside of the dog's eyelids, accompanied by symptoms such as redness and tears, and the dog will also be unwilling to open its eyes.

3. Exuded tears: If the dog's tears are discharged so much that it affects the color of the eye hair, it may be caused by exuded tears. Exudation of tears often occurs in light-haired dog breeds, and there are many causes of exudation of tears, which are usually effectively improved after changing diet.

4. Dry eye disease: If the dog's eyes cannot produce enough tears, it is likely that it is dry eye disease. Dry eye disease may also be caused by infection of the dog's lacrimal glands, or due to eye injuries or hypothyroidism. If a dog suffers from dry eye disease, the eyes will secrete yellow substances, and the eyelids will swell, and the frequency of blinking of the dog will increase. Dry eye disease can easily cause eye infections or corneal damage.

5. Glaucoma: The symptoms of glaucoma in dogs are the same as those in humans. Various reasons appear on the eyes cause tears to be unable to be discharged. Dog's tears are the best "weapon" to clean the eyes. If there are no tears, there will be other problems in the dog's eyes. Primary glaucoma in dogs is caused by the inability to discharge tears, which causes tears to accumulate in the eyes; secondary glaucoma refers to the eyes that have suffered certain trauma, such as inflammation, which can hinder the discharge of tears. Symptoms of glaucoma in dogs are mainly excessive blinking, swelling of the eyeball, elevated intraocular pressure, turbid eyeballs, diffusion of pupils, and decreased vision. Dog breeds such as Chow Chow, Poodle, and Cocker Spaniel are more likely to suffer from glaucoma.

The dog's eyes are very important to its life, so once the pet owner finds that the dog's eyes are uncomfortable, he should send it to the hospital for treatment in time.
