My fiancée and I were trying to check Zipper for a hair ring. He wouldn't let us, just kept squirming away. As he was doing so, we heard a "pop". My fiancee said it came from Zipper's leg. He's walking and hopping just fine. If a chin has a broken leg, will he be able to do that? We weren't holding him hard by any means! It happened as he was turning to run between both of our arms. I'm really scared, please help! Our vet is 90 minutes away and isn't open at this time of night. So I need to know.
