If you’re thinking about adding a furry family member to your pack anytime soon, this weekend is the time to do it!

Adoption fees will be waived at participating rescue groups or shelters in Alameda County, Contra Costa County, San Francisco and Santa Clara County for two days, Saturday, May 31 and Sunday, June 1.

This is all thanks to Maddie’s Fund, an organization dedicated to improving the lives of companion animals. They give a rescue or shelter from $500 to $2000 per dog or cat adopted during Maddie’s Days, the nation’s largest free adoption event. Those funds allow for the care and rehabilitation of pets who might otherwise be euthanized.

Maddie’s Fund has set a goal of 10,000 adoptions during this year’s Maddie’s Days.

If you are interested in adopting a pet for free this weekend, 90 shelters and rescues in four Bay Area counties are participating in the event.

A special event called “Rescue Row” will be held in San Francisco on Alabama Street, between 15th and 16th Streets. The event will feature food trucks, a beer garden, music and of course, adoptions! The San Francisco SPCA, Muttville Senior Dog Rescue, Northern California Family Dog Rescue and San Francisco Animal Care and Control, among others, will all be on hand with adoptable dogs and cats.
