Aren't yorkies a funny breed though. We have a 3 year old 4 lb little boy that is as tough as nails. We tried and tried to stop him jumping...impossible feat...and I swear he would chase down a great dane. Then we have a 2 lb little 5 and a half month old little girl who never tries to jump on or off anything thank goodness. She will go after squirrels but that is her limit lol. Then there is the aggressive little 8 week old puppy my relative is going to get that puts them both on the run. My two were a breeze to train but I am not sure if that one will be

. I have 7 grandkids and they play with my 2 but they have all been taught to be careful with them.
