Hi,
I am so happy to have found this forum. We have a 3.72 pound yorkie mix. We rescued Buttons (so named because we thought he was cute as a button) in late January of 2012. He weighed in at exactly two pounds. He was covered in fleas, was definitely undernourished and had dental issues. We later learned he had been tied to a bush outside in the cold weather. We don't know how long a period of time he was in this position. I am happy to say he is a smart, happy dog who delights us every day with his ability to tell us his wishes. We had two cats when we got Buttons. The older smaller cat would chase Buttons and Buttons would chase him. The younger cat did not and still does not want to play with him. Unfortunately, we lost the older cat a few months ago and I feel Buttons definitely misses that kind of interaction. We live in a condo that is relatively soundproof and Buttons isn't a barking dog. I think he would be happier with a playmate but my friend doesn't think so. I would be interested in thoughts any of you may have about introducing a new dog into this scene.
Buttons is pee-pad trained and because he is so little he doesn't go outside much. He does go to a groomer. Also when we first got him, he wouldn't eat any dog food so his diet is all regular food. We are working with a nutritionist to be certain he has a healthy diet. I don't know if a new dog was brought up on dog food, how this would affect both dogs.
Buttons can be shy with new people but warms up fairly rapidly if they are soft spoken and we are with him.
