Breeders are too often inhumane. Breed as many as possible, ditch the ones that don’t sell and can’t be used to breed more. My boxer is a rescue, she’s the sweetest thing in the world but is far smaller than healthy for a full grown boxer, and has taken years to not be afraid of everything. Vets say was used for breeding while too young, and likely borderline malnourished the entire time because she existed only to pump out litters of puppies. When she couldn’t anymore, she was abandoned.
