Parts ExpressDog, Soft Anti-Biting Barking Chewing, Breathable Waterproof Adjustable for Small Medium Dogs,Blue (XS)

Good for a 10lbs or less dog.

Xxs still to lg for my 7lb Chihuahua!

This muzzle was almost perfect. The fit was spot on for my dog (chihuahua/dachshund mix). My vet even asked me where I got it. My only criticism is that the fabric is a bit hard (firm nylon) probably a little better for bigger dogs.

Ordered for my puppy who likes to drink the bath water when we bathe her and gets sick. Ordered a medium and was a bit too small so when ordering, might want to go a size up.

I purchased this to help clip my dogs nails It was a great choice.

Xxs was Too small to fit My 7 lb ankle bitter

I bought an xx-small for my 4lb Pomeranian and this was too large. I hope this helps someone to help size their dog. She gets yappy during the middle of the night, so we were hoping this would help.If you're looking for something for your teacup/small pup under 5 lbs, I wouldn't recommend this. Otherwise, I'm sure this will work for slightly larger small dogs.

Dog was able to remove it.
