My name is Liz Bucalo. I am from Long Island and fostered hundreds of dogs. They mostly came from Southern states and most had never seen the inside of a house. While I do basic training with foster dogs, I am not a full time trainer. While fostering hundreds of dogs, I did my best to get them as manageable as possible so they had the best chance at getting adopted. The first time I used a "Gentle Leader" I was surprised by what a terrible design it is. First, you have to adjust it to make it fit on your dog's head, and, if you wanted to use it on multiple dogs, you would have to resize it every time. Most dogs automatically dislike having something on their face. They try to pull it off with their paws or rub it off on something. This is not a good time to be adjusting your equipment. I immediately came up with a better design than "Gentle Leader" I knew of a soft, yet very strong rope that is used for horse lead shanks, bridle and halter pieces. The fact that the Gentle Leader is attached underneath the dog's head (like a horse halter would) makes it automatically flawed. Horses heads are above your shoulder and dog's heads are usually a little above, at, or a little below your knees. This makes your leash connection to your dog farther away from the handler, and when the dog pulls, the Gentle Leader merely turns you dog's head by his snout in order to control him. Gentle Leader is also made from a flat nylon webbing that rides up under dog's eyes and can dig into their faces. "Not So Fast Rover" comes out behind your dog's head so that when they pull, the rope tightens and slows them down in a straight line. The handler has complete maneuverability to stop, change direction, change sides and back up. You can't do that with a Gentle leader without stopping, and walking in front of your dog to re-position yourself. This is very inconvenient.
