I am selling this item because I accidentally purchased the wrong size. I only put it on my dog's mouth once. This soft muzzle is gentle on a dog's mouth. It prevents unnecessary barking and is made of environmentally friendly materials. It also prevents the dog from eating things it shouldn't. - Color: Blue - Features: Bark prevention, eating prevention - Target: For dogs The adjustable range of the mouth strap is 11-43cm, allowing for better adjustment of wearing comfort without constricting the dog. This muzzle design helps prevent dogs from eating, allows them to breathe easily, and helps prevent barking and biting. Before purchasing a muzzle, measure the circumference of your dog's mouth and neck, and select the appropriate size according to the measurements. This is convenient for daily walks and is especially effective for dogs with a habit of barking.
