I've had dogs do both, perfect sits and sloppy sits as pups and as adults. Those adults that did sloppy sits lived to 15yrs old and while geriatric, still mobile... But, obviously having sloppy sits is not proper or they would not be called sloppy... SOOOO, my question is: What your thoughts on sloppy sits, is it laziness? Pain? Sign of problems? Literally sloppy and nothing to worry about?
