I have a 4 month old GS puppy that is driving me crazy! She is really sweet most of the time but then she goes in to her "puppy from hell" mode and theres nothing I can do to calm her down so I have no choice but to put her outside in the back yard. I hate doing that especially at night but I don't know what else to do. She has two more weeks til she gets her last vaccionations and until then I can't take her on walks or to the park to use up her energy. And when I get home from work i'm already so tired from my day that I need alittle time out for myself before I can effectively deal with her. She starts jumping up on me, biting at me, rips my clothes, and barks at me when I tell her no. When she's like this the only way to get her outside is to toss a treat out first then shut the door behind her real fast. I know this just sends her the wrong message and it makes me feel bad but i don't know what else to do. HELP ME PLEASE!!
