We use the quik fit muzzles at the shelter. They are easy to put on and adjust quickly which is what we need. The number 3 is the most used as we get in medium to large size dogs. It fits the lab size dogs with a long nose, some shepherds.

The number 3 is the one that is very close at hand when we need one. As a matter of fact we have two of this size.

Pros: easy to use.

Cons: none

Quick Fit Muzzles are the best. They're easy to put on and take off and it's a good humane way to muzzle your pet in cases where needed. I bought mine for one that is picky and snappy getting toenails clipped. We use them at the shelter in the vet clinic.

Pros: Easy to use.

Cons: Non found.

Our shelter uses the quick fit muzzles. They are so easy to use and have many sizes. The #3 is the one used the most if we do have to use a muzzle. We really do hate to use them. But for any vet clinic or shelter, quick fits are the ones to use.

They are easy to clean, adjusts easy.

Pros: affordable, easy to use

Cons: hate using them

These are good for short term use. These are not to be abused and left on. They are good for introducing dogs or vet visits.

Pros: good for introducing dogs

Cons: don't leave on!

I use this on my middle size dog, cause he gets a little snappy when I groom his tail. These are also great if your taking your dog for a walk and you want to be sure of the safety of your dog and anyone you may incounter. never let them loose tho keep them on the leash as they would have know way to protect themselfs in an encounter with another creature. I love this tho it gives me peace of mind when we're in new territory.

Pros: Excellant to use when your grooming the tail area

Cons: none
