Measurements Your Dog Needs to Fit In this Muzzle:
Nose Length: 2.25in-3in (66B) or 3.25in-4in (66) - 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.
Snout Width: 2.5-3.5in - This size is wide in the front; built for extra large bully type faces. It’s rare for any dog’s snout width to be wider than about 3.75” even in large dogs, so if you measured and got a larger width than 3.75”, please double check the measurement and/or reach out to us for help.
Cheek Width: 5-7.5in (Specify in form)
Full Pant Height: 7.5-8in - The muzzle gives about 8” of height, so if your dog uses less than 7.5” of open mouth height it will likely be uncomfortably large on them. Try the 65 for the next size down.
Head Length: 8.5 inches or longer
Nose to Neck Length: 4.25in or longer - If your dog’s nose to neck measurement is shorter than 4.25”, this muzzle will fit incorrectly and uncomfortably! Please double check this measurement!
