Quality breeders join Scottie clubs to learn more about the breed and to establish friendships with owners working for the welfare of Scotties. Ideal breeders breed only Scotties. Breeders of multiple breeds are usually commercial producers who are less knowledgeable about Scotties. Many responsible breeders do and also offer to take the Scottie back at any time in its life.
Many responsible breeders require their puppies be spayed and neutered.
These breeders want to prevent descendants of their puppies from misuse by puppymills or backyard breeders. They also realize that spaying and neutering reduces the risk of various cancers. Veteran breeders sometimes own both parents, but more usually do not. Rather, they choose a male with qualities to complement their female, even if that male lives 1,000 miles away. Most casual breeders know nothing about the health of their dog's relatives.
