My yorkie pup is either biting me and being really excited, or sleeping. Despite the fact he is only 13 weeks, his bites still hurt. I bought him chew toys and a "bully stick" (which is just a rawhide stick that he loves), but he rather bites me. Then, all of a sudden, he is calm and sleepy. How do I even out his behavior, or will it even out as he gets older?
