Query: looks nice, but inflexible and possible bad design

It is strong leather, but the strap and buckle are not very strong. I believe my APBT could break loose from this fairly easy, but it never came to that because the muzzle is a little big and he pulls it right off with a couple paw swipes. I think the paw swipes could probably break the strap though if the muzzle stayed in place. There is no flexibility to the muzzle so if it is not a perfectly snug fit from the start the dog will slip out easily.
