Hi, I should tell we've done a long way since we've got the first muzzle for Banjo until we got the one we use now. To tell you the truth, I knew nothing about dog muzzles and I suppose that made Banjo not very happy with my search. But I learned. I looked for information, people, and resources to help my boy to feel good with his muzzle on. Now Banjo loves his muzzle and comes gladly when he hears its sound. It is safe and comfortable. If I may say so, I like the way he looks with the muzzle on. Muzzles dogs are not bad dogs.
