Does any one else experience that their yorkies shake a bit? I have a 6 month old baby boy and sometimes he shakes. It is nothing that is so bad that it is deserving of a doctor but I was just wondering if mine was the only one that did this? My mother hasa 10 pound yorkie and she does not shake so this is new to me. I was thinking it is just because he is so small since he is always happy and never scared of anything!! Thanks!
