Sizing A Muzzle With Minimal Information
If you're on this page its safe to assume you either have a bite risk dog that is unsafe to measure, can't approximate or helping out a friend/rescue/shelter/foster etc that cannot get the info needed to size correctly. You could also be here as a groomer, vet or trainer looking for the most popular sizes/brands and which type of dogs they fit so you can keep some for your clients to use.
We do not recommend sizing based on breed/size/type. UNLESS your dog is a complete bite risk and unable to be measured; in that case, we would recommend asking MTT for help as you need to base the size off a full pant compared to closed height etc.
By using the information below and MTTs Dog Charts found HERE.
CHOPO:

-
1F/20C, 2F/21C, 3F/22C (GSD, Pointers, Labs, Doberman, smaller Great Danes etc.)

While there are other muzzles you can use, we believe the types above are the best for cost, safety and reliability after constant use.
For xs/small dogs you can look at the cheap set of plastic muzzles on amazon/AliExpress.
For dogs that are non bite risk, non scavenging you can look into using Baskervilles or greyhound too
