Grey Muzzle Hall of Honor

​The first Grey Muzzle Awardees were identified in 2007 and received their awards in 2008. Since that time the LHFI has presented Grey Muzzle Awards to both the breeders and owners of Leos that have reached the age of 12 years.
​
These are the canine equivalents of Centenarians, those humans who reach the 100-year mark.

As of 2020, the GMA presentations were revised to reflect a calendar year (January to December).​
