I just brought home a 8 month old Boxer, and she became very attached right away to me. She follows me everywhere will net let me out of her sight. She has never been trained by her prior owners. They never really house trained her, and never trained her any any commands. If I try and leave her, she rips up her cage and just carries on until I either come back inside and let her out. When I let her out she acts like she has not seen me for days. I have tried to give her a Kong toy filled with treats, but she quickly figures out how to get the treats ans she starts her tearing at the cage. Any help would be appreciated.
