Chloe just seems to be out of control! She bites and barks nonstop and terrorizes poor Chase. He has snapped at her a few times and she will stop for awhile but then start up again. He literally can't walk through the room without her jumping on him and I feel so sorry for him. Not to mention sorry for myself with holes in my arms and legs from her nipping. She is only 11 weeks old so I can't take her to any type of formal training yet. Any suggestions?
