The OFFA Website shows both sire and dam have had hips / Elbows tested good. They say the bitch is CNM N/N(clear). Bitch had CERF(cataracts) checked at one year old. They usually come on later if they do. I don't see anything as far as titles in either pedigree. I'd like to know the PRA status because it doesn't look like it's ever been checked through all the generations. No titles and minimum health clearances(hips/elbows only)
I'd say $500 is a fair price. Probably be a good pet and let the training you give determine all the other capabilities.
