Affordable veterinary care is worth the short drive. In 2025, 339 Brentwood pets came to The Pet Advocate in Tracy for spay or neuter surgery.
Cat neuter starts at $105. Cat spay starts at $130. Dog neuter starts at $170. Dog spay starts at $200. The clinic holds 4.8 stars on Google.
Published prices show the likely cost before you schedule. Weight, sex, and a few add-ons set the total.
Owner and veterinarian Dr. Mike Wesselink, DVM (UC Davis School of Veterinary Medicine, 2015) leads the practice. Dr. Megan Conlin, DVM, operates on the spay and neuter team. Pets stay in individual kennels. Pickup is the same afternoon.
We focus on essential procedures for healthy animals. That limited scope is how we keep the work efficient and the prices posted.

These are the published cash prices for low-cost spay and neuter. Confirm the current ladder on our prices and rates page when you book.
Canine pain tablets are $21. The E-collar is $18. We do not accept dogs over 100 pounds.
The listed fee covers anesthesia, monitoring, the surgery, and same-day discharge. Pain medication and an E-collar are optional. Together they run about $35. We recommend both.
Additional fees apply for obese pets, female dogs in heat, pregnant dogs or cats, and cryptorchid dogs or cats. Pets five years and older need pre-anesthetic bloodwork listed at $100.
Read the surgery requirements before you book.
If your pet falls outside that list, stay with a full-service Brentwood hospital. Two nearby options: Brentwood Veterinary Hospital, 4519 O'Hara Ave, (925) 634-1177, and Brentwood Family Pet Care, 121 Sand Creek Rd Suite B, (925) 240-7387.
Surgery is by appointment, Monday through Friday.
Fill out the consent form at home after it arrives by email. Withhold food and water from midnight the night before.
We call when your pet is in recovery and give you a pickup time, usually between 3:00 and 4:00. The full morning-to-pickup flow is on what to expect.
We accept TNR from anybody. The cat must arrive in a humane trap, not a carrier. Drop-off is 8:00 to 8:30. Booking is still required.
Individual caregivers pay the standard cat prices: $105 for a male, $130 for a female. Special pricing applies only to rescue organizations we already work with.
