March Muttness 2025

Get ready sports fans and pet fans! The Humane Society of Southern Arizona's March Muttness tournament is BACK!

39 animal shelters from across the country will be going head to head - or tail to tail - to save homeless pets. And YOU can help your team win!

March Muttness is beginning on March 1st! Donate to help the Humane Society of Southern Arizona and your other favorite shelters nationwide! Be a part of the excitement while saving lives!

How It Works

All 39 teams will begin play on March 1st for the Qualifying Round.

After the qualifier, the Top 32 will proceed with Round 1 of the Champion Bracket, followed by Round 2.

The Second Chance Bracket will also commence during Round 2, featuring the non-advancing teams from Round 1. This exciting sequence of events will unfold from March 13th onwards throughout the month of March.

We will have a March Muttness National Champion from the Champion bracket, as they make their way from the Snuggly 16 through the Furry 4 to the Championship Round. You won't want to miss the excitement!
