Unusual Behavior, Limping
I have an almost 2 year old jack russell. I noticed today that he seems to be favoring his front right leg, but isn't crying. He also hasn't eaten or drank anything today. I have no idea what he could've done to injure himself as I am outside with him every time he goes, and I have not heard him cry at all today, just noticed the limping this morning. Should I be worried?
