About Vet

I am a veterinarian practising in Toronto, Ontario. My father and sister are both veterinarians as well, so I am well-immersed in the profession. I have worked with all sorts of animals including dogs, cats, reptiles, sheep, cows, chickens, zoo animals, and more. I now primarily work with dogs and cats in the city and am happy to help in any way that I can.

I frequently help with concerns such as seizures, gastrointestinal upset, skin and ear issues, chronic disease management, medication questions, and second opinions. I aim to be thorough, practical, and honest, and to provide clear guidance you can feel confident about.

Dr. Sunarich was very professional and answered my questions thoughtfully. He was able to give me realistic expectations with many of the issues I brought up concerning my pet. I also really appreciated how he was willing to deep dive some of my more curious concerns. I feel much better after my appointment with Dr. Sunarich because I learned a lot and have a greater understanding of my pet's issues.

Dr. Sunarich was very helpful. He took his time to explain common dog behaviours to me and what to look out for with my first ever dog. I didn’t feel judged for my lack of knowledge. I felt like I could ask any question and get an honest and informative answer. Luigi and I are very happy with Dr. Sunarich!
