CHAMPION MUZZLES. A short review: This range of wire Basket style Muzzles is one that I use daily on two of my own big dogs that like to scrap, each other and anything else nearby. I have tried and used other muzzles in the past, like the fabric ones you could use for a quick visit to the vets and leather ones, but I found that these types were a bit restrictive and my dogs did not like having them on, the only leather one I liked was a very heavy duty 'ATTACK' style muzzle but felt that was a bit extreme for day to day use. The Champion Wire muzzles I have found to be very comfortable for the dogs with very good breathing and indeed drinking capabilities. They come in varying sizes and have ranges for types of dog, IE, Giant, Large, Medium, etc. with sizes given and how to measure your dogs head. I would recommend this range of wire Basket style Muzzles for use. This is one of my own dogs 'OZZY' GSD x Malinois mix breed wearing a Champion
