Devices and system are provided that can not only stop a pet from pulling its owner, but to train a pet over time to not pull while being walked on a leash. In an exemplary implementation, a cuff can be wrapped around the highest point of either front leg of a pet, using, for example a hook and loop fastener and running a leash through the sleeve or guide on the outside of the cuff, so that an existing leash can be run from the collar, under the inside of the leg and up to the owner's hand.
