My pup had hurt her leg pretty bad it seemed, because my daughter had put her on the bed and the dog paniced and jumped off. She yelped so loud I thought the dog broke her neck. Any way she had limped and cried constantly over the pain in her leg. Long story short it turned out she had sprained her little leg pretty bad, but with time she got to using it again and I hope that is the case with your doggy. I mean they can get hurt and because they are small it takes longer to heal then a bigger dog. GOOD LUCK SWEETY.
