On Saturday my deadbeat roommates put my dog outside to be chased around the neighborhood by the kids (very mean, Im looking for a new place to live) I have a 8lb Min pin chihuhua mix and he doesn’t bear weight on his back hind leg when on concrete. He walks on it fine when we’re inside on carpet. I’ve rotated it and wiggled each of his toes and he was not bothered by any of that. He doesn’t lick it or show any sort of pain other than just lifiting his little leg. He does have a little cut on the inside of his little paw so I’m wondering if that’s all it is. I’m sure its sprained so what can I do to make him more comfortable?

I was playing with my dog, and she was on her hind legs, then all of a sudden she started to wimper really badly and running away with her left hind leg clutched really tight.. i got a hold of her and then she calmed down, i put ice on it, but she still cant walk on it, is it sprained or broken?

How much would it be if i got an xray, or if it was broken or sprained. please help!!
shes a chihuahua, shes 7 pounds. she is holding it up, she isnt walking on it, when i move it she doesnt feel pain, she lies on her leg. is it broken or sprained?
she doesnt put it down, she just holds it up
I really want to take her to the vet, but my parents say shes ok. My mom is a nurse and she said we will observe her if she gets better then we wont take her, but if she isnt feeling better by mon we will take her she said.
