The way in which a dog is treated uaually only has something to do with this. Sure there are the dogs that are submissive because they have been beaten and kicked around. But, it is just how the dog is often. The most basket case, trembling, submissive urinating dogs I have ever seen have never had a hand laid on them. There are many members here that can vouch for thier soft pups and obviously treat them like royalty.
