Castro Valley Companion Animal Hospital

strives to provide the best veterinary care humanly possible: to alleviate pain, cure disease, and maintain the health of animals using all the skills, training and technology available to us; and to do so with the highest regard for the human animal bond. Our experience includes treating domestic and exotic pets including birds, reptiles, ferrets, fish, rabbits, dogs, and cats.
