Two Rock Dog Ranch started with a simple vision from Sue and Richard Harris: create the happiest possible place for a dog to stay. They wanted a place where dogs could run, play, splash, sniff, rest when they wanted to, and never feel alone. That vision became reality in 2002 when they opened Cotati Dog Boarding, which they renamed Two Rock Dog Ranch in 2009. Today, the ranch sits on 30 acres in Sonoma County just outside Petaluma, with room for dogs to be dogs in a safe, carefully supervised setting.
