I got my dog when she was a puppy. She is around two years old now and acts like she has gotten beaten her whole life. she will slump over and will rarely come over to you when you are standing up. when she does she will crawl over and roll on her back and pee. i'm tryin to teach her a few tricks now and she will just roll on her back and run away and lay behind a desk or chair. no one has ever hit her. i don't understand this. it seems like she will never be able to be trained. She's a golden retriever btw

I would take her to the vet and then to a trainer. I have never heard of a dog rolling on its back and peeing straight into the air. That sounds like a combination of a behavioral problem AND a medical (bladder) issue. The fact that she "hides" behind furniture, and that she slumps and crawls sounds more like she's sick than she's scared. When dogs don't feel well they lie in cool, dark places, often hidden in the shade of bigger items, like chairs or desks or tables. They isolate themselves from people and other animals.I had a Golden for 13 years, and she was the best dog; the breed is very smart, loyal, and loving, and they deserve the best care. I would definitely call your vet first thing in the morning, especially if this is a fairly new behavior. Something might be seriously wrong.Also please think about the people in her life: do you leave her with friends, family, or neighbors? How about doggy day care? just because you don't hit her, and you have never seen anyone hit her doesn't mean someone who was with her when you weren't might not have.
