dinkys are good if they don't eat through them
we stuck with a shires deluxe in the end, worn over night, one extra bit of fluff on the join between muzzle and throatlash and no rubbing.
I wouldn't personally use a greeguard due to rubbing and they have been attributed to enamel wear on teeth.
Dinky ones are really good They don't rub, all webbing and fully washable, air holes in the right place for the nostrils. Have tried a few but nothing compares to Dinky.
The shires ones with the sheepskin are my go to but my local store doesn't stock anything else.
Still, I like them, but the new forest has worked out how to get out of hers, so that's just something to be aware of if you've got a greedy native lol. (Though I'm convinced the shitland plays a role in these Great Grazing Muzzle Escapes because if you separate them the muzzle stays firmly in place ).
Dinky worked for us, though (as ester said) they do have to be replaced every few months due to the horse eating through them eventually!
Shires didn't work at all, mine couldn't figure out how to eat through the tiny hole.
once he'd had the dinky frank seemed to work out the shires hole pretty quick (the dinky took training, and a sacrificial one first, then he ate the second in a month ).
Given his teeth/jaw issues I'm hoping just tracking will be enough this year as don't want to muzzle.
Muzzles do not work for my boy as he has them off within 5 minutes or less, turning out for 2 1/2 hrs then in 3 hrs then out 2 1/2 seems to work for him.
My mare will only tolerate green guard muzzles. They have been a big help even over the winter. She has lost a good amount of weight and difinitly put it down to this helping.
I rotate between Dinkys (which aren't very restrictive but nice for them in wet/hot weather I feel) and Shires or Best Friend. The Best Friends are expensive but the best made IMO. I wont use a greenguard.
