We have a changed puppy now thanks to an invention called the Gentle Leader. It does not hurt the dog like regular collars do and she walks real nice the second try. Unbelievable ! If the dog you own pulls you or “takes you for a walk” instead of you walking the dog, try one! You will be glad you did. It comes with very good directions for putting it on and adjusting it and many other training tips as well. My Goldendoodle has adjusted to it real quick.
