Isn't there something in the bible that tells man to treat animals well or something?
Sounds like they need Cesar Millan.
But seriously, dogs need discipline, love and care. It's a balance. How does your boyfriend feel about how his dad is? Does he agree with the way his dad is raising animals?
Also getting smaller dogs is a TERRIBLE idea if you don't discipline them. They run around, bark like crazy, jump on laps, jump at you, etc
