The front door is clearly labeled to let dogs know this is the way in; it's a "Dog's Entrance" leading to a decorative, oversize pawprint path leading along the linoleum floor to various strategic locations indoors. Surprisingly, many dogs seem to know their way around here. Or maybe they are just used to following their masters. At any rate, Acorn's caring doctors and staff treat dogs and many other cherished animal companions in Davis. They're also ready to help their human companions cope by using humor and a caring manner. A longtime Davis institution, Acorn hosts weekly vaccine clinics and informs the community about current disease threats. Specialty pet foods and accessories are also sold here.
