Advanced Treatment, Delivered with Heart
Fullerton Pet Clinic isn't a typical veterinary practice. We combine cutting-edge diagnostics and technology with care that feels personal — because your pet deserves treatment that's as attentive as it is precise.
Care That Grows With a Relationship, Not a Chart
You won't see a different face every visit. At Fullerton Pet Clinic, your pet stays with the same trusted team — one that knows their history, their quirks, and what's normal for them. From routine wellness checks to more complex cases, we build care plans on honest conversation and a relationship that carries over from one visit to the next.

How much does a vet visit cost at Fullerton Pet Clinic?
Fullerton Pet Clinic publishes itemized prices for exams, vaccines, spay and neuter, dental cleanings, surgeries, and health certificates on our Pricing page, including a reduced exam fee for new clients. Because every pet is different, any procedure starts with an in-person exam, so we can't quote exact costs by phone.

Yes. Fullerton Pet Clinic is open Monday, Tuesday, Thursday, Friday, and Saturday from 8:30am to 6:00pm, and Wednesday from 8:30am to 1:00pm. We're closed on Sundays. Saturday hours mean your pet can be seen without waiting until Monday.

Yes. Fullerton Pet Clinic welcomes walk-in patients during business hours, though a scheduled appointment costs less and usually means a shorter wait. Walk-in wait times depend on the day's schedule, so call or text ahead if you can.
Compare exam feesWho is the veterinarian at Fullerton Pet Clinic? Will I see the same vet every time?
Fullerton Pet Clinic is owned and run by Dr. Kee Eun Lee, a graduate of Seoul National University's College of Veterinary Medicine who completed a clinical year at Oklahoma State University's College of Veterinary Medicine through the PAVE program. He brings experience in general practice, urgent care, and emergency medicine. You'll see the same team at every visit, so the people treating your pet already know their history.
Meet Dr. LeeDo you spay and neuter dogs and cats? How is it priced?
Yes. Fullerton Pet Clinic spays and neuters both dogs and cats in-house, with anesthesia and vital signs monitored continuously from start to recovery. Dog prices are set by weight, and cat prices are flat; the consultation, pre-surgical bloodwork, and post-op medications are billed separately.
See spay and neuter pricingWhat's included in a dental cleaning, and is anesthesia necessary?
Every dental cleaning at Fullerton Pet Clinic is a bundle that includes pre-anesthetic bloodwork, full-mouth digital X-rays, anesthesia, cleaning above and below the gumline, and polishing; extractions and take-home medications are extra. Anesthesia is required: it's the only way to clean below the gumline, where dental disease starts. Following AAHA guidance, we don't offer anesthesia-free dentistry.
See dental pricingWhat vaccines does my puppy or kitten need?
We follow AAHA vaccination guidelines. Puppies need the DAPP series (at least three doses between 6 and 16 weeks), leptospirosis from 12 weeks, and rabies by 4 months, which Orange County law requires for dogs. Kittens need the FVRCP series, FeLV, and rabies by 4 months. Lifestyle vaccines like Bordetella and canine influenza are recommended for pets who are boarded or groomed.
Vaccine schedulesCan you do X-rays, bloodwork, and ultrasound in the clinic?
Yes. Fullerton Pet Clinic has an in-house blood analyzer, digital X-rays, and ultrasound, so most results come back the same day. Skin and ear samples are checked under our in-house microscope in minutes. For advanced cases, we refer to board-certified radiologists and cardiologists.
About diagnosticsDo you do TPLO and other orthopedic surgery?
Yes. Fullerton Pet Clinic performs TPLO for torn cruciate ligaments, FHO, and luxating patella repair with a board-certified mobile surgeon, so your pet has surgery here with a team that already knows them. A consultation comes first to confirm your pet is a good candidate and which procedure fits.
Orthopedic surgeryDo you offer pet wellness plans?
Yes. We offer wellness plans through Snout, built around your pet's life stage and focused on prevention and early screening. Senior pets are best seen every six months, since age-related changes are easier to manage when caught early.
