How do I get my dog to stop being a jerk?

Clearly the pup is in control when it comes to your husband and she knows it. The pup is doing normal puppy things and your husband allows it which then just makes you the bad guy. She is testing the dominance chain and hubby is at the bottom if she is him and being aggressive. As she becomes ually mature she will display dominance in a very firm way with him and he will be very sorry he didn't remember this time in her life to show her who is really the dog and who is the human. I do not mean being unduley harsh but to show her what behavior is acceptable and what is not. If you both don't get a handle on her behavior right now you're in for several rough years with this dog. How will you medicate her if she needs it? How will you bathe her? How will you get her to do anything like come to you if there is a dangerous situation you trying to keep her from.(Like eating out of the trash) And on a side note a dog that digs in the trash and is allowed to WILL at some time in their life have frequent gastro-intestinal upsets and/or need surgical intervention to remove a foreign body from the stomach or intestines. Your husband is NOT doing anyone any favors by letting her get away with this behavior, I promise you ! Good Luck!
