The number of dogs in Weim rescue is staggering. If you breed, it is expected you will accept the return of any unwanted dogs produced by your breeding. Environment plays a role equal to genetics. I have euthanized wonderful dogs that came from people that were not educated to the needs of Weims, and I have put down genetic nightmares that were sold to wonderful families. There is more to puppy rearing than simply feeding and waiting for the puppies to come of selling age.
Proper conditioning is extremely important for the attitudes of the puppies too.
Blue Weimaraners Blue Weimaraners do not occur naturally in the breed, like chocolate labs, for example. Blue Weims are created through an extremely limited gene pool, originating from one dog named Tell, who was imported from Germany in 1942. He was imported under the provision that he would not be bred or provide stud service, which was disregarded. It is not the AKC that has disqualified blues, but the parent club, The Weimaraner Club of America, which acts as the guardians of the breed. Blues may still compete in performance events.
