I recommend having your pet's eyes examine ASAP. Your dog may have a condition called enophthalmos or sunken eye. This occurs when a retractor muscle spasms and pulls the eyeball back into its socket. When only one eye is affected, the most likely cause is a painful eye, often due to eyelid irritation, corneal abrasion or ulceration, or foreign material in the eye. Following a severe eye injury , the eye can also shrink and sink into its socket. Treatment is based on diagnosing the underlying cause of the sunken eye.
