An australian shepherd, and a blue heeler mix. Bought a size large for a 45lb (but large headed/long nosed) border collie. Fits my greyhound & galgo perfectly.

Threading it through a collar (or threading the collar strap through the collar) helps prevent this. When my family leaves the house my dog chew door/window frames, furniture, and barks for hours.

These muzzles are lightweight, soft and very well made and solved our pica problem. Sturdy, with enough room to pant, just as advertised.

Simply awesome muzzles. All in all satisfied with this purchase.

She wears a muzzle to protect her and any other dogs that may come up. Little kids love her pink "mask" the only negative is the plastic seems to irritate the top of her nose after long use and wish it had a thin piece of fabric for comfort.

Very disappointed. Do not recommend. Actual useful height of this muzzle is really only 4.

This just isn't it for my heeler. Debating whether to return or just cut the chin strap off and rig up something a bit longer. Maybe my pup’s head is odd to size lol!
