This muzzle is the best I have found for my unsocialised farm kelpie because the strap which goes over her head can be undone and attached to her collar so that she can't pull it off. She has pulled every other muzzle off when I take her to the vet. She is extremely protective towards me. It is also great for breathing as well.

Not very good, it lasted 3 wears, he managed to pull it off, I had to put extra strapping to hold it on, he got it off and chew it up so now useless, maybe a wire one may have been better

Arrived within a few days. Good fit for a big dog.

My toy cavoodle chewed through it in 4 days, while it was on her face.

It arrived quickly, fits well and my dog was happy to wear after the initial confusion.
She can drink easily with in on and is happy to go for an hour walk with no problem at all.
