Okay, so I have this pretty hyper dog thats sorta difficult to train. Her name is Cookie and I managed to train her "sit", and "lie down", and "up!". But now I really want to teach her to "roll over". I told her to lie down and put the treat behind her and near her back or near the back of her neck to try and lure her to roll over. But she thinks she gets the treat already so instead, she jumps up from her "lie-down position" and tries to swallow the treat!! She's not the best dog to train, so I need help!! Does anyone know how to properly train a hyper dog to roll over?? Thanks!!
