Sadie almost got a clean bill of health today at the vet's except for one thing - Her knees. She loves to play frisbee with me and sometimes I've noticed her favoring one leg or another after she lands from leaping in the air after the frisbee. The vet examined her joints and says that her knee cap slides in and out of place on both of her hind legs. She says that it's not serious and that Sadie doesn't necessarily need surgery at the moment.
Have any of you had experience with this kind of problem?
