I considered doing this at one time, but we decided to move and then we adopted 2 stray dogs that were in the area. I asked my vet about it and there was an assistant there that had adopted one. She said they were wonderful sweet intellegent dogs. The one drawback was that they don't live long:-( She said since they are large dogs, they have a shorter life span and all the racing usually shortened it more. Good Luck! I still think I may adopt one sometime.
