Oh trust me there was no other signal. When my puppies start to live with the older dogs I watch their interactions very carefully. I do know my dogs and after 24 years of breeding dogs I know what pups are like.
Ethical breeding is easy to talk of but this is not quick or straight forward fix. And breeders haven't been sitting on their hands. Things are underway.
Again it's a Dal breeders choice what they want to do. If they are of the belief that a pup should be given a chance then there is a very simple solution don't join the breed club, doesn't mean they are not a member of the ANKC. If their school of thought is otherwise join the Dal Club in their state.
