I recently bought some muzzles for my Newfoundland Henry, who suffers from chronic skin disease. He was forced to wear a dog cone all the time to prevent licking and biting himself when itching. It was difficult for him to drink and to be at home. This muzzle became a discovery compared to everything I used before, even much more expensive. The design fits perfectly around his mouth, it is quite light and adjustable to fit snug. Now we can leave him alone for a while and we know that he can feel comfortable at home and drink water easily with the muzzle on. Unfortunately we have to use a muzzle sometimes when he is alone. I recommend this muzzle. Make sure you have made the correct measurements. I thought to add to the measurements but the muzzle has enough space and many straps to provide convenient and reliable fit as I said earlier. I also recommend a quick-release buckle.
