i have an 8 week old chow puppy who got his first shots today he seemed fine afteward he was palying and running around but about two hours he started to cry in pain, he seems too be all sad and starts to cry when he gets up or walks so he will just sit in place, he has eaten but he has not gone to the restroom, we started to rub his back (which is where he gots his shots) and he seems to be hurting there because he started to cry....is this normal beahvior for a puppy who just got his shots or should i be worried?
