The clinical course can range from 6 months to 1 year before dogs become paraplegic. The weakness gets progressively worse until the dog is unable to walk. As the disease progresses, the limbs become weak and the dog begins to buckle and has difficulty standing. This can first occur in one hind limb and then affect the other. The affected dog will wobble when walking, knuckle over or drag the feet. It begins with a loss of coordination (ataxia) in the hind limbs. The disease has an insidious onset typically between 8 and 14 years of age. They were Degenerative Myelopathy (DM) and Exercise Induced Collapse (EIC).ĭegenerative Myelopathy (DM) is a progressive disease of the spinal cord in older dogs. They will not develop PRA-PRCD and will, if bred, pass the mutation to 50% of its offspring, on average.ĪT RISK/AFFECTED: These dogs have two copies of the mutation associated with PRA-PRCD which typically results in complete blindness for most breeds. This was great service in my opinion.Īll three PRA-PRCD test results were indeed Clear/Normal which was indicated by a “A” on the certificate.ĬLEAR/NORMAL: These dogs have two copies of the normal gene and will neither develop PRA-PRCD nor pass this mutation to their offspring.ĬARRIER/NOT AFFECTED: These dogs have one copy of the normal gene and one copy of the mutation associated with this disease. I sent in the test swabs on Friday July 15th, I received the results/certificates online on Friday July 22nd. to have a certificate of proof of their results. I wanted to test each of them so I could 1. Gambler, Glory and Guilty I suspected were Clear By Parentage (CBP) which means their parents were tested for this disease and were found to be clear of the disease so they would of passed the clear genes onto all their offspring. It is important to note that other inherited eye disorders can display similar symptoms to PRA-PRCD. Although rate of onset and disease progression can vary by breed, PRA-PRCD typically results in eventual loss of sight and complete blindness in affected dogs. Most dogs begin to show symptoms of the disease at approximately 3-5 years of age that manifests as difficulty seeing at night (night blindness) and loss of peripheral vision. These cells are important for vision in dim and bright light. It is an inherited eye disease with late onset of symptoms that are due to degeneration of both rod and cone cells of the retina. Progressive rod-cone degeneration (PRA-PRCD) is one specific type of PRA that affects many dog breeds. Progressive retinal atrophy (PRA) is a category of different progressive conditions related to retinal atrophy that can eventually lead to blindness. The test I had run on Gambler, Glory and Guilty was for Progressive Rod-Cone Degeneration (PRA-PRCD). Today I am going to talk about the Genetic tests I had run and the results. Last week I wrote about Canine Genetic testing through GenSol Diagnostics, if you missed it you can read about it here.
