Typical dog behavior being an opportunist. When we get accustomed to a stable diet, she will probably curb that habit.Pooping in the flower bed and stealing food off of plates? Yeah, you've got your work cut out for you!
No, just verbal, a lot of praise for good behavior, ignore or softly shut down with no punishment for bad behavior and the look. She loves to walk in front of you and lay down on her back expecting a tummy rub. Almost tripped my wife doing that. I have never praised her for that I always ignored or shuffled my feet toward her. She gets the message I'm not slowing down and she's in the way. She then slinks again toward the door trying to escape. If she isn't sleeping she wants attention or chews her toys.Do you train with a clicker/snaps?
We have a Houdi also that earned his name the same way.
