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.

How much does a vet visit cost at Fullerton Pet Clinic?
Fullerton Pet Clinic believes in transparent pricing. We publish itemized prices for exams, vaccines, spay and neuter procedures, dental cleanings, surgeries, and other common services on our Pricing page. We also offer a reduced exam fee for new clients.
Because every pet's needs are different, procedures and treatments require an in-person examination before we can provide an accurate estimate. For this reason, we're unable to provide exact treatment or procedure costs over the phone.
See our pricingWhat are your hours? Are you open on Saturdays?
Yes. Fullerton Pet Clinic is open Monday, Tuesday, Thursday, Friday, and Saturday from 8:30am to 5:30pm, 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.

Request an appointmentDo you accept walk-ins?
Yes. Fullerton Pet Clinic welcomes walk-in patients during business hours, subject to availability. The walk-in/same-day exam fee is $89. Same-day availability is limited and depends on the day's appointment schedule and patient volume, so we may not be able to accommodate every walk-in patient.
Scheduled appointments have a lower exam fee and typically a shorter wait time. We recommend calling or texting us at (657) 655-4393 before coming in to check same-day availability.
Compare exam feesWho is the veterinarian at Fullerton Pet Clinic? Will I see the same vet every time?
Fullerton Pet Clinic is privately owned and operated by Dr. Kee Eun Lee.
As a privately owned, intimate veterinary practice, we focus on building long-term relationships with our patients and their families. You'll see Dr. Lee and the same veterinary team, allowing us to get to know your pet, understand their medical history, and provide consistent, personalized care at every visit.
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 includes pre-anesthetic bloodwork, full-mouth digital dental X-rays, general anesthesia, professional cleaning above and below the gumline, and polishing. If extractions or take-home medications are needed, those are additional.
Yes, anesthesia is necessary for a thorough and safe dental cleaning. It allows us to properly examine and clean below the gumline, where periodontal disease often develops, while keeping your pet comfortable and still throughout the procedure.
Following AAHA dental care guidelines, Fullerton Pet Clinic does not offer anesthesia-free dental cleanings.
See dental pricingWhat vaccines does my puppy or kitten need?
At Fullerton Pet Clinic, we follow AAHA vaccination guidelines and tailor each vaccination plan to your pet's age and lifestyle.
Puppies typically receive a series of DAPP vaccines starting at 6–8 weeks of age and continuing until at least 16 weeks, along with Bordetella. Rabies vaccination is given at 12 weeks of age or older.
Kittens typically receive a series of FVRCP vaccines, along with FeLV (feline leukemia) vaccination based on age and risk. Rabies vaccination is given at 12 weeks of age or older.
Lifestyle vaccines, such as leptospirosis and canine influenza, may also be recommended based on your dog's environment, activities, and exposure risk.
During your pet's visit, we'll review their vaccination history and lifestyle and recommend an appropriate vaccine schedule.
Vaccine schedulesCan you do X-rays, bloodwork, and ultrasound in the clinic?
Yes. Fullerton Pet Clinic offers a wide range of in-house diagnostic services, including bloodwork, digital X-rays, ultrasound, and microscopic evaluation of skin and ear samples.
Our in-house blood analyzer allows us to obtain many blood test results the same day, while digital X-rays and ultrasound help us evaluate your pet without having to visit another facility for many common diagnostic needs. Skin and ear samples can often be examined under our microscope within minutes.
For cases requiring a more advanced ultrasound evaluation, we can arrange for a mobile board-certified veterinary radiologist to come directly to our clinic to perform the ultrasound.
About diagnosticsDo you do TPLO and other orthopedic surgeries?
Yes. For orthopedic procedures, we arrange for our mobile board-certified veterinary surgeon to come directly to Fullerton Pet Clinic to perform the surgery. Procedures available include TPLO for torn cruciate ligaments, FHO (femoral head ostectomy), and luxating patella repair, allowing your pet to receive specialized surgical care at our clinic with a team they already know.
An examination and consultation are required first to evaluate your pet, review any necessary X-rays or diagnostic tests, and determine whether surgery is appropriate and which procedure is recommended.
