Obedient Pup Vision Blocker, Dog Blinder, Training Aid (XL) Get control of barking, lunging and fearful behavior!: Similar to "horse blinders", Obedient Pup helps to control your barking or lunging dog while walking on a leash or when your dog is anxious. When your dog sees a distraction (or better yet, you see it first!), causing him to react fearfully or with barking or lunging on the leash, you can quickly pull the Obedient Pup's unique visual blocker over your dog's eyes which will help to bring your dog back to a calm state-of-mind quickly. It's easy, quick, effective and gentle!:When there is something that your dog might see that is exciting or upsetting, just pull the Obedient Pup neck gaiter up over your dog's eyes to block his or her view for a few moments until the distraction has passed (while you feed your dog yummy treats!). Once the distraction is gone, simply pull the Obedient Pup back down around your dog's neck until needed again. Comfy too: Made of a soft, lightweight, stretchy cotton blend. No straps around your dog's face to irritate him or her. Can be worn as a neck gaiter until needed. Other things we love: Handmade in the USA! Machine washable. Neutral tan with brown edge. Seller note: We recommend that you before you begin using the Obedient Pup, you first teach your dog that having the hood pulled up over his or her head is rewarded with yummy treats. This will create a positive association to the feeling of the Obedient Pup and will help to speed your training.
