about a month ago i got a dog that is yorkie mixed to be a friend for my other youkie mix. someone had put the dog in a fence of my friend. the dog must have been abused for he was scared of me, wouldn't play or didn't know how to play. now with a month of work with my yorkie and me the dog is now happy and playfull. yes he sometime goes into a shell but for a very short time, he now is happy and plays not only with me but with my yorkie. his name is king now, so when your dogs sees him they must bow down to him because he is the king of the dogs.
