It's great that there were multiple muzzles to try to find the one that fits your dog the best, but unfortunately, none of these fit mine (shiba inu). The small was too small and the one after that was too big. He also managed to get it off him pretty easily, though it's probably because it was too big for his long snout.

I ordered the Midnight Black backpack but they sent a gray one. The prodcut itself seems good quality but 4 stars--I'd give it 5 if they had sent the one I wanted.

I've been using the braided stretch belts with the normal buckles for about 10 years now and they keep breaking down over time and becoming a nuisance. I bought these hoping that the buckle and belt material would solve the problems I've been having from the other belts, and so far it seems hopeful. The included buckles are easy to use and grip the belts across the full surface which should prevent the belts from breaking down so quickly. There is just enough stretch to move with me without being too tight. The only downsides so far: The width of the belt, I believe, was described as 1.5" which is almost too wide to fit into some of my belt loops. The only other problem I've noticed so far is that the belt is a little thin and stiff, that mixed with the height of the belt causes it to make contact with my lower back waist when sitting which is very uncomfortable.
