I have a 9-year-ol lab/shepard (?) mix. Several days ago he started having difficulty with his back legs. At times he has difficulty getting up while sitting or laying down. I don't know if he has pulled something or is getting arthritis or something more serious. He has no other symptoms and has been a healthy dog. He gets moderate exercise and before these symptoms he had been on a short hike and then a short run the following day. Any info would be appreciated.
