I've got 2 chins both born in may a couple weeks apart. The younger of the two, Sam, caught his front paw between two bars at the bottom of the door to his cage and twisted his paw and/or leg around as he was jumping in from my girlfriend's hand. He hasn't used his paw since and it's been about 3-4 hours. He's still hopping around his cage and eating and seems fine ,although he's obviously less energetic This could be due to the extended playtime he had before going back in. He pulls away when I touch his paw to try and check it and wont use it at all. Is there a large possibility it's broken or dislocated? Should I see if it's doing better in a day or two before taking him for x-rays or is it imperative to his health that he goes now?
