OSN is closed on Sundays. If you feel your pet is having a medical emergency, please seek treatment at your nearest emergency clinic, or Inland Valley Veterinary Specialists and Emergency Center located at 10 W 7th Street in Upland. Their phone number is 909-931-7871.

Our mission is to make sure that everyone has access to low cost spay and neuter and quality yet affordable veterinary care. Our vision is to join the coalition of forces that is working to end unnecessary euthanasia and to ultimately reduce the number of homeless pets and shelter intake.
