|Dogs can have many of the same eye diseases people can. In older dogs, especially, cataracts and glaucoma are quite common.
Cataracts can occur in very young dogs, middle-aged dogs, and senior dogs. Some breeds are more prone to developing cataracts than others. Cataracts can occur due to other diseases such as diabetes mellitus (sugar diabetes).
Glaucoma can result from injury to the eye, and can be hereditary. It is considered to be an emergency condition. If it is not treated right away, blindness can develop.
If you notice changes in the color or shape of your pet's eyes, or your pet squints, rubs its eye, or shows other signs of eye pain, contact your veterinarian.
