Low Cost Spay & Neuter

To help stop the pet overpopulation crisis at its source, ARF's Spay & Neuter Clinic opens its doors to community pets for high-quality, affordable spay and neuter services. ARF's compassionate and experienced veterinarians and technicians use state-of-the-art equipment to surgically sterilize thousands of dogs and cats each year using the highest standards of care.

Spaying or neutering your pet prevents unwanted litters and eases the burden faced by overcrowded animal shelters. Altering can also help dogs and cats live longer, healthier lives by lowering the risk of reproductive-related health problems and reducing undesirable behaviors driven by the urge to mate, such as marking, spraying, or roaming. 

Appointment Hours

Mondays and Wednesdays: Drop off 7:30-8 am, Pick-up same day 4-5 pm. All services are by appointment only; no drop-in services are available.
