Training harness. Size: S Color: Black & Silver Brand: PetSafe *The outer box will be removed, and the item will be shipped as is. About this product: This training harness is made by the American manufacturer PetSafe, utilizing a dog's natural behavior. It can naturally guide the dog to the side, making it easy to control pulling without force. By attaching the leash to the front of the chest, the dog is less likely to go ahead of the owner. When the leash is pulled, the martingale loop tightens, reducing the dog's forward pulling force. It doesn't choke the dog's throat even when the leash is pulled, so there's no worry about breathing difficulties or vomiting. Training can be done without putting a burden on the dog. Easy to put on with buckles on the shoulders and belly. Once you adjust the size, you can put it on quickly.
