One Health - Healthy Pets, Healthier You

Uniting pet and human well-being through awareness, compassion, and practical care.

Because pet care isn’t just about them — it’s about you, too.

Hello,

Dr. Justin Mercado here!

I go by different nicknames but you can call me Doc Just. I’m a licensed veterinarian in the Philippines, AVMA ECFVG-certified, a devoted pet parent to my late cat Boljy, and someone who shares practical, everyday pet-care advice I’ve learned as a professional.

Over the years at the clinic I’ve seen too many incidents that could have been prevented with awareness. That frustration became a mission: to guide pet owners on what truly matters.

Here you’ll find money-saving tips, clear pet-health insights, and a bit of human-centered wisdom—because healthy pets start with informed, confident people.

Vision

A better place where pets and their humans suffer less — through awareness, prevention, and shared responsibility.

Mission

To simplify veterinary knowledge and promote practical, preventive care that protects both pets and their people.

5 Things

You Might Not Know About Doc Just

ONE

Spectrum of Pet Care

I'm the author of the e-book Spectrum of Pet Care. The title was coined after a long time of wondering for the term what the primary goal of the book content is about. I'm already been practicing the concept long before I encountered the term "spectrum of care" even though it already existed for some time.

I Became a Veterinarian

Aside from the usual "I love animals", I'm also very fascinated to the science of animals. Their unique individual features such as furs, feathers, scales, etc. I grew up watching animal planet and national geographic channel and I think that's a factor why my dad offered me to take the course of veterinary medicine even though I'm not aware of the profession at first.

Pokemon

I grew up with the presence of Pokémon. Watching the tv series, collecting trading card games, playing in Gameboy, figurines and stuff toys. The fun thing is that Pokémon are derived from real world animals and that's one thing I enjoy seeing animals, whether in the clinic, outdoors or the zoo. I swam with whale sharks in their natural habitat and it was AWESOME!

One Health Approach

I'm an advocate of one health approach which introduces the interconnectedness of human, animal, and environmental health to achieve optimal health outcomes for all. The reason for this is that I frequently encounter some patients with poor environment setting that made them sick leading to pet owner frustration and stress. Addressing the three areas holistically can solve the problem as a whole. A healthy pet starts with a healthy owner and environment.

Professional, Player

At work I practice my profession. On days off, I play trading card games, mobile games, Beyblade battles, basketball or pickleball. I consider playing or anything that makes you feel happy an important part of well-being as these are hacks to your happy hormones. I believe life is short not to enjoy. I'm no professional at any games but I just enjoy them.
