Aly first of all I can see why you are in love with Rascal because I am too!! Yorkies are another favorite breed of mine! Has he met Lolly, Reece and Shiloh yet? I think you might find your answer there. He sounds like he might be a bit difficult for Shiloh to accept, although you can't know for sure unless you try. Since the girl is coming today I doubt there is much time for you to introduce him to your gang if you haven't already. It sounds like he will be going to a good home so, if you don't get to have him for yourself, just rest in that. Somehow I have a feeling that Rascal will be able to hold his own with a Rottie!!! Those little Yorkies just don't seem to realize they are so small!!
