We regret to announce that due to extenuating staffing circumstances, OSN will be temporarily closing on Sundays beginning September 2, 2018.
We apologize for any inconvenience this may cause our wonderful clients and hope to reopen on Sundays as soon as possible! We will still be open regular business hours Monday through Saturday. If your pet is having post-surigcal complications from a surgery performed at OSN that you do not feel can wait for our open business hours, please call the clinic to speak with an after-hours technician. If your pet is having a medical emergency, please seek treatment at your nearest emergency clinic, or Inland Valley Veterinary Specialists and Emergency Center 909-931-7871 at 10 W 7th St in Upland.

 
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.
