Clinic Notice

Temporary Clinic Closure Notice

Fullerton Pet Clinic will be closed from October 12 through October 19 while Dr. Lee attends an overseas veterinary conference.

During this time, our team will still be available to send medical records and assist with prescription refills. However, patient appointments, examinations, and treatments will not be available until the clinic reopens.

If your pet may need medication during this period, we recommend requesting refills in advance.

We apologize for any inconvenience and appreciate your understanding. Thank you for trusting Fullerton Pet Clinic with your pet's care!

Care you can trust, from a team you'll love

Diagnostics

Accurate answers. Personalized care. Peace of mind.

Routine Diagnostic Tests

Fecal exams, heartworm tests, and annual blood work aren't one-size-fits-all. We choose the tests that make sense for your pet's age, breed, and history, rather than running a generic checklist.

Skin & Ear Diagnostics

Most skin and ear issues can be diagnosed on the spot with our in-house microscope — identifying cocci bacteria, rod bacteria, yeast, and fungi in minutes rather than days. For more complex or resistant cases, we send samples to a reference lab for a closer look.

In-House Diagnostic Equipment

Blood Analyzer

In-house bloodwork, so we're not waiting days for basic answers.

X-Rays

Digital imaging for bones, organs, and foreign objects.

Ultrasound

A closer look at soft tissue and organ function without surgery.

Referrals

For advanced cases, we refer out to board-certified radiologists and cardiologists.

Expert Interpretation

A test result is only useful when someone who knows your pet is reading it. Every result comes back to Dr. Lee, who already has your pet's history in mind, so you get an explanation, not just numbers on a page.
