He's probably just frustrated that he can't move around like he wants to. But just keep showering him with attention and he will get better. Yorkies are very emotional, also. He wants your undivided attention. My Chewy had Valley Fever last year and we had to force feed her, among other things. But, she would lay around and cry a lot. When they don't feel well, they let us know. I spent a lot of time just holding her and reassuring her. I will continue to keep you guys on my praryer list. Things will look up. Thank God he's made it this good so far! Hang in there!
