The Petlife Halti Head Collar combines comfort and control, it is manufactured with soft yet strong nylon webbing, with a soft neoprene nose band for added comfort. Simply attach your lead to the Halti's connecting ring and see the improvement. As your dog pulls away, the Halti will gently close your dogs mouth, which is a sensation they will not particularly enjoy. As they stop pulling, the Halti will release the pressure to reward your pooch. In the early days of training, enhancing reward time with a tasty treat will encourage your pooch to walk calmly beside you at all times! The Petlife Halti still allows your dog to pant, yawn and drink while they are out and about, while still providing excellent correction.
