So I brought my 9 mo to the yard to play some fetch and when I picked up her ball I threw it up and she jumped up to snatch it but she missed and came down and landed weird on her back legs. She immediately started whining and was limping and holding her right leg up. I had her lay down for a little bit and her whining stopped but then she got back up and began chasing her ball again. And she was doing so with intensity. But when she tried sprinting it seemed like her run looked a little odd. My question is what to do with her. Should I still let her in the yard to run around a bit and exercise? She seems like she doesn't feel any pain anymore as she has resumed her jumping and running in around 10 minutes. Im just scared that it is badly damaged or could get worse if she does too much.
