Don't be fooled by the name: supporting the Dumb Friends League is a very smart decision. The Denver-based organization, founded in 1910, was named after the British animal shelter Our Dumb Friends League. "Dumb" was used to describe animals back in the day because they don't speak a human language; today, that concept is present in the league's mission statement of "speaking for those who cannot speak for themselves." Twenty-five thousand lost and abandoned animals every year are "spoken for" by the Dumb Friends League through sheltering and care, along with the following services: pairing homeless pets with new owners, reuniting lost pets with their owners, reviewing cases of animal cruelty, backing animal-friendly legislation, teaching animal behavior assistance classes, listing pet-friendly housing in Colorado, providing education on humane animal treatment, and giving donor-financed spaying and neutering to pets in underserved communities.

The Dumb Friends League, founded in 1910, is headquartered in Denver.
