my yorkie was 1 1/2lbs when we got her at 7 weeks old. She is will be 9 weeks old this sunday Jan.26th. She seems to eat good ,about 3-4 small meals a day. I feed her Iams puppy lamb and rice and Iams puppy dry food. Should she have gained weight by now? or is this normal for such a small dog.She also gets plenty of rest as we have no children or other animals but we also make sure we play with her as often as we can which seems to be plenty.
