Her behavior is normal, but DO ignore her and DO stick to your guns.

Your pup is crying and begging and will continue to do so for the next few days. This is called an "extinction burst". Think about it: if she has been allowed on the couch for the past few years and you suddenly revoke these privileges, she will try to jump back on because that has been acceptable behavior in the past. But when you don't concede to her, she'll only try harder because experience has taught her that begging and crying used to work. The more you ignore, the harder she tries until she finally gives up. This is the extinction of the behavior. Think of it as a child's temper tantrum

Re: your hubby's philosophy. I have to disagree with your hubby's training methods and agree with you in that it IS only exacerbating her aggression. Every single time you allow your dog to aggress, you reinforce its behavior. It does not matter if you punish her for aggressing, the fact is that aggression is self-reinforcing. The fact that she displays it at all means that she has inadvertently reinforced it. Your job is to PREVENT the aggression from appearing at all. If you allow her to aggress, you're only reinforcing it.

A note on punishments: Punishments are often misused and it sounds like your hubby is misusing it. Punishments must be 1) severe 2) lasting 3) occur every time the bad behavior crops up. This makes them very tricky to use. If you punish your dog, but she seems entirely unfazed or she easily slips back into the bad behavior, that means the punishment is neither severe nor lasting. Punishments must be severe to work. That's what makes them so difficult to use properly, and that's why I try to avoid recommending punishments at all. Just reward the good behavior and prevent the pup from aggressing in the first place - and stick to your guns!!
