Question: Dog Pannus (An Inherited Health Defect) “My daughter-in-law is blind and has a seeing eye dog. The other day, I noticed her dog’s eyes looked a little filmy. Two veterinarians both agree it was pannus. They gave her drops to put in three times a day for the rest of the dog’s life.”

To understand the various reasons why your dog may come down with a serious eye problem, you need know some important information on the genetic make-up of these animals.
