We were just guessing, have no idea if pano is in Ruby's background or not. It could have been an injury (you know how those crazy Lab pups jump around, and she could easily have twisted something) but the lameness moved from one foreleg to the other and then back again, then it went away. It seemed to be slightly painful (but not enough to keep her from jumping around like an idiot - just enough to make her limp, and whine when you pressed on the bone).
But it went away, and hasn't come back. Which is a good thing.
Sorry, that last post was for you! Don’t know what I was thinking - I guess about Holland, or something!
Sure sounds like pano. Pano is not genetic. LOL, the hard part is keeping her still.
