There’s something about a pair of big puppy eyes or the soft purr of a contented cat that can turn even the hardest person into a puddle of mush. What better way to show your appreciation for the joy your pet brings to your life than to party all the Do Dah Day? Literally.

Do Dah Day is one of the United States’ largest and longest running animal festivals and fundraisers. This year marks the 31st anniversary of the event, and it will be held on May 15 at Rhodes and Caldwell Parks in Birmingham, Ala.

Do Dah Day started in 1979 with a small group of friends and has grown into a giant music festival that welcomes more than 40,000 people from all over the U.S. each year. It has raised more than $536,000 for Jefferson County animal shelters since 1992 and has managed to remain a 100 percent volunteer organization.

You don’t have to live in or travel to Birmingham to be a part of Do Dah Day. You can contribute via to help make a difference in the life of a dog or cat that needs you.

Do Dah Day has a vast array of activities to take part in. The party kicks off on the night May 14 – aka, Do Dah Eve – at 7:01 p.m. The crowning of the Do Dah Day king and queen will take place at 11:01 p.m. On the following Saturday there will be a parade, a dozen bands performing, and a special kids area with fun activities for the entire family.
