Dog Eye Ulcers. A dog eye ulcer is usually called a corneal ulcer. A corneal ulcer is an abrasion to the top layer of tissue lining the cornea which is the clear part of the eye. Canine Corneal Ulcers are the third most common eye problem in dogs. Many eye ulcers are caused by trauma from foreign objects like fox tails and seed hulls from grass and weeds that can lodge under the eyelid. Scratches resulting from rough play between new puppies and kittens are also a common cause.
