WOW thank you so much for your response and the website information. My last GSD, I purchased from a "back yard breeder" she was a Belgium Shepherd. She also was my 4th GSD. I had never heard of DM before her. She also had other things wrong with her. I have since her death(7 weeks today) I have been on the AKC websites and researched several breeds. I have also been to several Rescue Shelters and spoke with Foster Parents of different dogs. I would be happy with a young adult. I have researched the following breeds, Border Collie, Aussie, Golden Doodle, and a couple of others. My vet mentioned that Golden Doodles were a pretty good dog to have. I know that as you say it is expensive for a breeder to give DNA test, etc for specific issues with a breed. I know that the Border Collies have eye issues, thyroid, hip and can be allergic to certain heart worm meds. I also know there are tests for these which can be given to the litter. I worry about getting a dog from a breeder which may have a bad reputation and I wondered how I would find one reputable. All the websites look great but one never knows. I did check the State Licensing and found one breeder who license was revoked. Not a good sign.
What type of dogs to you breed? In the meanwhile thank you so much for responding to me you have been a big help.
