About Vet

Hello! I’m Dr. Katelyn Harrington, a California-licensed veterinarian. I completed my Doctor of Veterinary Medicine degree at St. George’s University, followed by clinical training in the United States. I’m passionate about helping pet parents feel informed and confident in their pet’s health, and I look forward to supporting your furry family member.

I help dogs and cats with: • General medicine & everyday concerns • Skin issues (itching, allergies, hot spots, infections) • Digestive problems & nutrition guidance • Chronic condition support (arthritis, endocrine disease, recurrent GI upset) • Mild behavioral concerns (anxiety, stress-related issues) • Preventive care, wellness planning & second opinions • Integrative medicine approaches for mobility, inflammation, and overall wellness

My telehealth approach is warm, practical, and judgment-free. I focus on giving pet parents clear answers and actionable steps, whether you’re dealing with a new issue or ongoing health management.

Such a great experience. She was kind, knowledgeable, and took the time to really listen and review everything. I never felt rushed, and it was clear she genuinely cares about animals (especially Frenchies!). I’m very grateful for her help and would absolutely recommend her.

Dr. Harrington was the best vet I've seen on this platform. She suggested extra steps to prevent problems from getting worse for my old dog. She was able to prescribe the medications he needed and explained everything wonderfully. Thank you, Dr. Harrington! Bentley is going to be much happier after our visit! :) I will definitely return to her if I have any other issues or pets in the future!
