I found myself in the same positions .I bought a male for breeding in S.E.Missouri from a kennel owned by Debbie McCabe named
www.delmacyorkies.com . I bought him when he was 5 month old. She assured me he would be a great little breeder for me, there were no problems at all in his lineage. 2 month after I had him he started to have severe seizures. She wanted nothing to do with the dog or me when I called her about it. I spent about 500 dollar getting him straighten out, then gave him away to a good home. Released his papers after they had him fixed. And this woman still breeds the dog that producted this pup. I learned a good lesson, Be every careful when buying a dog get everything in writing.
