Fairly urgent question re: grazing muzzles

[Skhosu]

ok, so dug out a grazing muzzle from last year, it seems to fit the connie well. Now he did a few snorts in it and was not amused but no heavy breathing etc.
So I need to know how tight should it fit as I am concerned about it being too loose and blocking his nose? He's out at the moment with it on and seemed ok although less than amused. It's a shire's bucket type one. I wondered about cutting some of te fabric off around his nose so I could clearly see his nostrils..
Anyone any suggestions?
I could go and take it off but surely they're designed not to inhibit breathing?

are you talking about the nylon muzzle or a plastic one? My pony wears a nylon shires 24/7 and he is fine.

nylon. thanks, just worried in case he can't breath! It fits without any bother, I just worried that the holes aren't big enough. But I'm just being silly, thanks!

He will be fine, I use those too.

yes...have just looked out and he is guzzling as much as he can through it, so it stayed on and obviously hasn't killed him,

thanks
