Why will my puppy not play
We got our JRT just over a month ago from a breeder. She was 10 weeks old when we got her. She was the runt of the litter. So adorable...but it seems that all she wants to do is sleep. She constantly walks around with her tail tucked and her back hunched. She is so sweet when she plays which is not very often. She seems like she is so sad all the time. What could be wrong or what do we need to do. Right now she is about 16 weeks old. I thought that she should be a little more playful by now.
