My Snorkie has stopped jumping.
My 2 1/2 year old male snorkie (miniature schnauzer and yorkie mix) used to jump on the couch without a problem. Recently he stopped jumping all together. He has to be coaxed to jump and then sometimes he doesn't. Now he has started to whine when he does decide to jump. Goes for walks doesn't seem to bother to him. I've given him infant tylenol and that seems to help. Any ideas as to what the problem could be?
