PHS/SPCA is a private, independent, non-profit, and our scope of services goes beyond that of a so-called no-kill, or limited admission, facility. As an open-door shelter, PHS/SPCA accepts all animals brought to us, regardless of age, breed or size, and we’ve rehomed 100% of the healthy dogs and cats in our care since 2003 and promise to do this going forward. While rewarding, this isn’t our most challenging work and doesn’t define us. We accept our community’s sick, injured, abused, unwanted, stray, neglected and older animals; donations to our Hope Program enable us to help and rehome approximately 200 every month. (Sadly, private shelters in many communities never give them a chance). We rehabilitate wildlife, make spay/neuter free for our low or fixed-income residents, educate children, and investigate animal cruelty. PHS/SPCA is one of the few shelters in the entire state accredited by the American Animal Hospital association and we’re a gold-level GuideStar Exchange participant (click the seal below to access our GuideStar nonprofit report). We take our work and mission seriously, but also have fun. It's why we've adopted "Sit Happens!" as our Behavior & Training Dept slogan and have "Go Nuts” emblazoned across the back our of mobile spay/neuter clinic. Most important, we’ve earned our community’s trust, involvement and support.
