Eye problems in dogs can result from a injury or eye health conditions. Conjunctivitis is an infection of the eye that causes pain and inflammation. Pus can accumulate around the eye causing extreme discomfort. Dogs also can develop vision problems or age-related conditions such as glaucoma. However, some small breeds such as chihuahuas have over-active tear ducts, which can be mistaken for eye problems.

Itchy Eyes
-
Eye problems in dogs can cause itching. Itching is a result of irritation from an infection in or around the eye. Your dog will itch uncontrollably, which makes the problem worse. If your dog has itchy eyes, take him to the veterinarian. He may need to wear a plastic cone head covering to prevent him from scratching his eye. He also may need antibiotics to treat an infection.
Inflammation
-
One of the most common signs of eye problems in dogs is inflammation. Inflammation causes the eye and surrounding tissues to swell and become red. If your dog's eye problem is due to an injury, the inflammation will naturally go down as long as the injury is not severe. However, if your dog suffers from inflammation due to an underlying medical condition, the problem will be recurring and likely will get worse over time.
If inflammation is severe, this may be a sign of something more serious such as cancer of the eye or bleeding behind the eye.
An infection located on the eye lid only is called blepharitis. Your dog's eye lid will swell and droop, making it difficult to see.
Diminishing Vision
-
Vision problems are common in older dogs. As your dog ages, her sight can decline from cataracts or other problems. Some dogs become blind in old age. Some signs of serious visions problems include: cloudy eyes, glaring or constant blinking. A dog with vision problems also may bump into things, stare at the wall or try to concentrate on an object.
