I was brushing Oliver tonight and I noticed a little clott of blood on his head. As I was washing it away I felt a small bumo underneath (like a swollon, human, bruise) He had hit his head yesterday-- he was doing the crazy yorkie running around in huge circles thing and ran underneath the bed and bumped his head on the metal frame!!!

I was wondering if puppies were like humans and might get a bad bruise that would swell. I'm really worried about him, now. Has anything like this happened to anyone?
