WHAT IS "P.R.A" IN A DOG?

I just googled PRA because I didn’t know what it was either. Thought others would like to read about it too. Progressive Retinal Atrophy (PRA) in Dogs This is a genetic, inherited disease of the retina (the “film” in the camera), which occurs in both eyes simultaneously. The disease is nonpainful, and there is no cure for it. The eyes are genetically programmed to go blind. PRA occurs in most breeds of dogs and can occur in mixed breeds also. It is recessively inherited in all breeds studied, with the following exceptions: PRA is dominantly inherited in Old English Mastiffs and Bullmastiffs, and PRA is sex-linked and found primarily in male dogs in the Siberian Husky and Samoyed breeds. Clinical signs vary from the dog first becoming night blind in the early stage of PRA (not able to see in low light surroundings) to the entire visual field in all light levels becoming affected, which is advanced PRA. The pupils are usually dilated, and owners often notice a “glow” and increased “eye shine” from the eyes. All dogs with PRA will eventually develop blindness from advanced PRA, and this time frame until the dog is blind varies considerably from dog to dog, but usually takes at least 6 months from the time of diagnosis, and can rarely take years until the dog is completely blind. Although no treatment for PRA is possible to stop the disease, nutritional antioxidant supplementation for retinal health may help slow the deterioration of the retina to “buy some time” before the blindness inevitably happens. Animal Eye Care believes that in many of these PRA patients, specific oral antioxidant nutritional therapy can delay the progression of blindness. Blindness is not avoided, however, in any PRA patients. If oral antioxidants were used, they would be continued until complete vision loss occurred.

Hope this was not to long I got this from a post on hotdogblog.com my other place I hang out...
You all have a great week see you tomorrow.... Buddy
