you are not alone with this. We got a rescue Yorkie 1 1/2 weeks ago. And he eat like never got food before. Now he does eat alot slower. He also marks his area. That is what the older gentleman taught him to do. The vet said beings not been fixed and almost 2 years old. That will probable not stop, so now he wears a belly band when out of his pen. He also was not use to being in a pen. But now when we are gone or he poops in the house he know that is where he has to go. Deiter also would not let Cozmo on my lap with out going after him. That now has subsided. I know where you are coming from with all that you are going thru. Hang in there. Just remember that they both have there own personality. That is what won my heart over with Cozmo. It took 1 week for me to get attached to him. Now I love him too.....
Hang in there it takes time. But Cozmo is coming around slowly but we are working very hard with this.
