Hi, Hoping to get some help on this one. My three year Labrador has been displaying some strange behaviour when chasing a ball. We will throw the ball a few times and everything will be fine but then she will start acting strange like she has hurt herself and is very uncomfortable. Please see video attached. She will then lay down for a bit and seem injured but will then jump back up and keep chasing the ball like nothing has happened. She is generally very fit and goes on lots of works without doing this. Its only when chasing ball. We have taken her to the vet and she was all good muscularly and skeletally. This was just by feel without scans. Hoping someone has seen something similar before and can tell us a bit more about the issue and if anything can be done or if she is fine and no reason to worry. Thanks
