For example, «The Trainers from the Dark Side» recommend teaching a
dog not to jump up by shouting at the
dog; squirting him in the face with water or lemon juice; swatting him on the nose with a rolled - up newspaper; yanking on the
dog's leash; hanging the
dog by his choke - collar;
squeezing the
dog's front
paws; treading on his hind
paws; kneeing the
dog in the chest; or flipping the
dog over backwards.
