The Best Mount Shasta, CA Dog Rescues & Shelters in 2026

Siskiyou Humane Society Inc.

“The Siskiyou Humane Society exists to improve the lives of companion animals by sheltering, rehabilitating, reducing pet overpopulation and finding permanent homes. We promote responsible pet ownership, kindness to animals and enhancement of human-animal relationships through education and outreach.” Since its founding in 1968, the Siskiyou Humane Society Adoption Center in Mt. Shasta has provided rescue and refuge for hundreds of homeless cats and dogs every year. The shelter’s staff and volunteers take special pride in getting to know the animals as individuals. Because they are familiar with the personalities of the shelter cats and dogs, they can help potential adopters find the best matches for their families and lifestyles. All pets adopted from SHS are vaccinated, spayed and neutered and given permanent micro-chip identification. Siskiyou Humane Society is a “no-kill” facility, animals aren’t euthanized because they’ve been in the shelter for too long, or to make room for more animals, but are cared for until they find new homes. Preventing pet over-population is a big part of the Society’s mission statement. The shelter provides information and referrals for low-income Spay/Neuter assistance programs in Siskiyou County. SHS also offers humane education presentations for schools, youth groups and service organizations with topics like dog-bite prevention and kindness to animals. SHS also operates a Community Pet Resource Center in Yreka, where we provide pet owners with vital resources such as free microchips, a pet food pantry and supply essential pet supplies to owners in need of support. As a private, 501(c)(3)non-profit animal welfare organization, the shelter receives no funding from government agencies or national humane organizations. Most of the funding comes from private donations, grant funding and the sales at the Humane Society’s thrift store in Mt Shasta.
