That's great news!
Not to hijack your thread, but back in 1995, we bought a black German Shepherd puppy from a reputable breeder with the idea of having a good home-protection dog. The initial dog we got was a male that we named "Jo Jo." The breeder had informed us that if there were any health issues discovered within first few months he would take the pup back. Well, very shortly after we got him home, we noticed something was wrong. He would have short bursts of energy, but then run out of steam and just plop down on the floor, seemingly with no energy. We took him to the Vet and he wasn't sure of the problem, but suspected a hole in the heart. We were sent to a doggy heart specialist in Santa Fe who confirmed it - Jo Jo had a
Patent ductus arteriosus (PDA) (hole in the heart). The prognosis was grim without a very expensive operation which we simply could not afford at the time.
Initially, we were going to just give the Pup back and get a refund, but then the Doc in Santa Fe, seeing how upset we were, told us that he might be able to have Jo Jo's heart problem fixed for not cost. But the deal was, we would not get the dog back. We spoke to the breeder and he agreed to let us "donate" Jo Jo to the veterinarian teaching hospital in Ft Collins, Colorado. All I had to do was drive Jo Jo to Ft Colllins, CO. They were able to use Jo Jo as a teaching opportunity for new vet students and fixed his heart. Then, the deal was, they would give the dog to the family of one of the Vet students. A few years later, out of the blue, we received a nice letter from the new owners, with a picture of Jo Jo - they had re-named him "Heiner" (yuck). Anyway, "Heiner" lived a long healthy life.
In the meantime, when it was clear Jo Jo had this serious health issue, the breeder allowed us to pick a different pup from the same litter at no additional charge. We ended up with his sister, also a black pup, who we named "Sadie." Sadie lived 14 years. She had a healthy life, but we found her deceased one day out in the dog run. At the moment we are without a dog, but are thinking about another German Shepherd. They are very loyal and make great home protection dogs. Here's a picture of our Sadie:
