Was outside my yorkie who is 3.1lbs and 9 weeks old was on the groung playing I ran inside to get my drink and when I went back 5 seconds later he was yelping and whinning but still on the ground I can't think of what he could have fallen from I grabbed him and ran inside my boyfriend looked at him and we found a splinter we got it out and he stopped whining. I have moved his leg all around and nothing he does not seem bothered if you touch his leg and he will put a little weight on it but he is still limping. I don't know what to do I am thinking of giving it overnight since right now he is sleeping but any thoughts we are thinking his paw is just sore.
