You'll need a tape measure (or ruler) and your dog.
Each step has photos to guide you.
Send us your measurement photos — we'll double-check before building.
How to Measure Snout Circumference
This is the full circle around your dog’s snout, measured just behind the nose. Ideally, take this measurement while your dog is panting, but it’s okay if not — just be clear about which one you measured.
💡 Tips:
- If your dog isn’t panting, leave enough extra room to account for pant space.
- Be clear in your notes or photos whether you measured while panting or not. It makes a big difference.
Pro tip
Pro tip: A little extra room is better than too tight. Dogs need space to open their mouths comfortably in the muzzle.
How to measure pant height
This measurement tells us how tall the muzzle needs to be. Measure from the top of your dog’s snout to the bottom of their jaw, ideally while panting, but it’s okay if not.
📸 Photo required: Please include a picture of a ruler or tape measure held next to your dog’s mouth. This helps us double-check your measurement and makes exchanges simple if needed.
💡 Tips:
- Smaller dogs (under 25 lbs) need extra accuracy — every fraction matters.
- Most dogs don’t fully pant in photos, so plan for a little extra room beyond what you see.
- Think about your dog’s lifestyle: heavy panters need more space, light panters may need less.
Pro tip
If you’re unsure, upload your measurement photo. We’ll help confirm before building your muzzle.
How to Measure Snout Length
This is the distance from just below your dog’s eyes to the tip of their nose. This measurement is critical because it determines how long the muzzle will be.
📸 Photo required: Please include a clear picture of a tape measure running along the top of your dog’s snout.
💡 Tips:
- Accuracy matters — most dogs fall between 2.5–3.5 inches, while longer-snouted breeds (like German Shepherds) can reach 4.5 inches or more.
- Extra space in front of the nose = more room to breathe, pant, drink, and take treats — but it can also cause the muzzle to push up toward the eyes when sniffing close to the ground.
Pro tip
There’s no “one right way” here — it comes down to your dog’s needs and your preferences. Think about whether you’d like your dog’s nose right at the end of the muzzle, or with a little space in front.
How to measure snout width
This is the width of your dog’s snout at its widest point.
📸 Photo suggested: A picture with the tape measure across your dog’s nose helps us confirm placement.
💡 Tips:
- Biothane is flexible, so this measurement doesn’t need to be exact.
- It’s okay to round up to the nearest half inch.
- Smaller dogs need more accuracy, while larger dogs have more wiggle room.
Pro tip
Don’t stress this one too much — close is good enough.
