Good muzzle

I purchased this muzzle for my over zealous Aussie. Who is led by his emotions. Bite first.Ask questions later kind of guy. The muzzle was used effectively as a training aide, without any slip offs or mishaps.

I believe there may be a typo in the instructions. If I put it on my dog going by the picture, (the larger space it on the top )
It doesn’t fit well and he can not drink with it on or receive treats. But flip it over.., it contours to his muzzle better, eats and drinks. There isn’t enough space to bite, unless you stick your fingers in there.

The only thing I would like to see, on an updated model, is some kind anti chafe liner? For the bridge of the nose. It rubbed him raw if he had to wear it for more than one hour.
