Kumfi Dog Safety Muzzle Size Large - humane and comfortable calmer

It may be relatively comfortable, however, my dog managed to get it off 3 or 4 times on the first outing: I now thread the clip through the loop in his collar and that seems to do the trick but that makes putting it on/ taking it off a lot more fiddly. He also tore the fabric in several places by rubbing it along the ground/ through barbed wire - it could do with being made from slightly tougher material. Having said that it does calm him down and the company make other products, such as a double ended lead, which I'm going to try. I'm also going to purchase a cage type muzzle to see if he prefers it and it might allow him to pant in hot weather - this muzzle is quite tight.
