Tethering is foundational I would do this even with a puppy. ESPECIALLY with a puppy haha! Doing this from a young age will help immensely! If you have a dog who: - Struggles to settle - paces - doesn’t handle frustration well - doesn’t handle restraint well - wants to be in control - hyperactive - has separation anxiety - constantly follows you This is a great addition to your training. I love this technique because the leash does all the work. They can throw their tantrum and you just sit back
