Yes I read the article. I have bought dogs from breeders and bred dogs as well. FWIW, Field trial champions, both beagles and retrievers. I believe that in most cases a rescued dog is fine. Nowadays that may be different. Its been a few years (cough
decadecough) since I've been involved. Aside from some very specific cases, I see no need to breed more animals that we already have too many of.
This includes cats
(ducks and runs)
