Puppies desperately need to know who is Alpha in the pack as they grow up to become good dogs. If it isn't clear to them they assume they are the dominant member of the group. (See photo above.) It is very stressful for them to have a bad owner who won't LEAD AND COMMAND but will yell at them and threaten them when they do what to them is a natural part of pack behavior.
It is very distressing to see a decently bred dog maltreated. But, Bo, we know how it feels when the guy who is supposed to be in command doesn't know the first damn thing about leadership.
