If your dog is anxious or gets motion sickness, a sedative eye patch will calm your dog down. Calming Dog Eye Patches make it easier for you to groom your dog, such as bathing, trimming paws, cleaning ears and cutting hair. When doing minor surgery or physical examination without anesthesia, the dog’s anti-emotion can be relieved and it is easier to cooperate. The material is mainly nylon, which is light, durable and waterproof. Size L: Mouth 7.09"-10.24", Neck 10.24"-22.83"
