About My Dog Trainer

Welcome to M.D.T - My Dog Trainer


My Dog Trainer started as early as 2005, and was officially registered in 2008 by Al Chong and Cheryl Goi, M.D.T has come a long way from its beginnings in a one-room kind of home office, in the east of Singapore. When Al first started, his passion for dogs, he thought to himself how nice would it be to have a job that he can have his beloved Golden Retriever (Gody) alongside him. And that was how the tagline “Working as A-Team” came about.


Moving on to helping dog owners to understand more about their dog’s behavior, providing the most up to date research on dog training and behavior drove him to do intense research, and gave him the impetus to turn hard work and inspiration into a business/passion, clients to being friends sustainable dog training business.

“Avian Behavior and Training with Debbie Foster – Debbie Foster, CPBT-KA and CPBC”

Date Time: Feb 20, 2021 01:00 PM Eastern Time (US and Canada)

Description: Join us for a class that will teach you the science of learning and behavior and learn how we can apply that to the birds in our care. This class is good for people who are new to parrots and for people who have had parrots for quite a while. We guarantee you’ll learn something new!

You’ll get information on how and what to train, and understand the connection between what we do and our bird’s behavior.

Debbie is certified as a trainer and behavior consultant and combines those two disciplines to help people with their parrots and to help give birds the skills they need to succeed in their homes. She is also an instructor at Companion Animal Sciences Institute, a teaching assistant for Living and Learning with Animals, and the owner of Parrot Ps and Qs.

Date Time: Feb 27, 2021 01:30 PM Eastern Time (US and Canada)

Description: What can bird droppings tell us about their health? What are our avian veterinarians looking for when they do gram stains? Dr. Rhyne of Birdhouse Mobile Exotic Vet covers all you may have ever wanted to know (and more) about bird droppings! She’ll also share information about safe and effective cleaners and disinfectants, and how and when to use each. Join us!

The COVID-19 pandemic has challenged all of us to come up with creative ways to maintain our well-being — for people and pets included!  In this webinar, Dr. Mehrkam will share how the theories and principles of behavior analysis and the psychology of learning can be applied to training and enrichment plans for companion animals, while considering the latest data and research on CDC guidelines and how human-pet relationships are affected by the pandemic. Dr. Mehrkam will also explain how Monmouth University’s new virtual Applied Animal Behavior Research Clinic has provided both online and in-person education on humane, evidence-based behavior modification for novice pet owners in the community. By the conclusion of the webinar, attendees will be able to take away enrichment and training ideas you can try at home with your own dogs, cats, and yes, even goldfish.
