    Put this on my dog for Halloween and my neighbor literally jumped back off her porch 😂 He just sat there wagging his tail the whole time. Ordering a second one before it sells out.

      Measure your dog’s snout circumference and check our size guide (XS–L). If you’re between sizes, we recommend sizing up for a more comfortable fit.

      Yes — the jaw is openable, so your dog can pant and move its mouth naturally, it just can’t fully open wide or bite down.
