I agree 100% penny. Jamie's dame belonged to our neighbor. I helped her whelp Jamie's litter mates and they gave me Jamie as a thank you gift. He was a sweet natured boy who's mom was purchased at a local pet shop. Strange thing was he was the only pup out of 3 litters to develop PRA and early onset kidney failure.I am so Sorry both are hereditary and can be eradicated by breeding more selective and always knowing your bloodlines genetics.. I will step off my soapbox now
