Puppies can be sooooooo exhausting. If this isn't working for you, then you should not have to try to deal. You are right, you and your puppy should be well matched. While puppies are more work than adult dogs normally, they shouldn't exhaust you as this one has. No matter what the reason is....talk to son and tell him what's happening....your health is most important here!
