Size 20 Standard Muzzle
Best fit for medium sized narrow-snouted dogs, often around 40-60lbs. Breeds that commonly fit into this size include medium-large sized herding/cattle dogs, border collies, and medium-small shepherds.
As of February 2026, Select Standard muzzle sizes, including this Size 20, will now come with Powder Coated Glossy Black baskets instead of Rubber Coated baskets. Powder Coating is a thinner, more light weight coating than rubber coating.
Our Standard Big Snoof Muzzles include Color Customizable Genuine BioThane Straps, Adjustable Nosebands, Rust-Resistant Silver Hardware, Customizable Cheek Widths and Adjustable Quick Release Buckles.
NECESSARY MEASUREMENTS LISTED IN THE DESCRIPTION BELOW. MAKE SURE TO CAREFULLY MEASURE YOUR DOG ACCORDING TO OUR GUIDES BEFORE PURCHASING TO ENSURE YOU GET THE RIGHT SIZE. Feel free to email or DM us with measurements for recommendations! We want to help ensure you get the best possible size the first time!

Measurements Your Dog Needs to Have to Fit in this Muzzle:
Nose Length: 3.25-3.75in (20) - DO NOT ADD LENGTH, a bit of extra room is accounted for. Go by the actual length of your dog’s nose as measured according to our Measurement Guide. Remember to include the length of their lips/mouth if it protrudes further out than their nose does!
Snout Width: 2.5-3in - This size is narrow in the front; built for shepherd type faces.
Cheek Width: 4.5-6in (Specify in form)
Full Pant Height: 5-5.5 inches - The muzzle gives about 5.5” of height, so if your dog uses less than 5” of open mouth height, it will likely be uncomfortably large on them.
Head Length: 7.5 inches or longer
Nose to Neck Length: 4.5in or longer - If your dog’s nose to neck measurement is shorter than 4.5”, this muzzle will fit incorrectly and uncomfortably! Please double check this measurement!
