I am so sorry that you feel it nessisary to do this, but if it is best, then it is best. I have a friend who owns a heeler a bluish colored one but I think it is a mix with border collie, this dog doesnt act like a heeler at all or a border collie but looks just like them. I think that he just has the herding instinct, some pups dont and that makes them not working or show quality! I hope that he finds a good home.
