Description: The front opening does not affect breathing, so that it's comfortable to wear. The inner layer is thickened with soft cushion design to reduce friction and protect the pet. With the mask on, the dog's mouth can still be slightly opened and not tightly closed. It solves the problem that the traditional dog's mouth can't drink water without pressure. Can be adjusted according to the size of the dog mouth, stable and fixed. Specification: Colour: red. Material: Nylon. Size: XS, S, M, L, XL. Size: XS, Adjustable range: 9-12cm.
