Gives you total control when walking your dog. The soft nylon collar fits around its face without restricting the mouth. If the dog tries to pull or lunge forward, Halti transfers the forward motion into turning the head sideways. This immediately discourages the activity. Size 0 fits Toy Poodle, Yorkie.

Free safety strap included.

I gave the Halti head collar three stars because it was recommended to me by a trainer and because it did work. Our beagle is a timid dog, which led to some aggression caused by fear and by her being uncertain of her status. The Halti mimics the pressure that mother dogs put on puppies' snouts to discipline them and also makes it difficult for the dog to pull.

Molly's behavior was greatly changed on walks. In fact, it changed so much that it was sad. She walked solemnly and joylessly, looking neither to the left or the right. She hated the Halti, and we had to chase her down to get her to let us put it on. Even though it has been a year since we stopped using it, we still have trouble sometimes getting her to come when she thinks we are going for a walk.

Most discussions of the Halti emphasize that it may take a while for your dog to grow accustomed to it. Molly never did. In fact, we owned two because she chewed the first one up. Maybe it was just normal chewing, or maybe she was sending us a message!
