Update on my yorkie herd:
So I took everyones advise and decided to foster him for a bit.
Inital introduction went MUCH better than expected. My dogs usually like other dogs but especailly Chibi can get growly and a little jealous. Chibi immediatly was happy and friendly and everyone had waggy tails. One problem- Molli (surprise

). I know its a bit early to tell but I am worried Molli may be a bit too much for "Oliver" (what I've been calling "Skully"). She keeps pouncing on him and he looks scared and sad. Oliver is in a little ball on the couch next to me now but has not tried to play yet. We will see if he warms up more tomorrow but if my wild child continues to torment him I dont think it would be fair to keep him.
