Over the past three years, Hu worked as an apprentice dog trainer in Arlington, Virginia and volunteered at numerous animal shelters in the US. Hu and his wife moved to Toronto with their Beagle/Vizsla mix, Bear in the summer of 2018.

Hu has loved animals since he was a child, growing up with dogs in the family. After obtaining a Bachelor’s Degree of Art in Media Production in United Kingdom, Hu worked as a TV producer in Beijing for five years. During that time, he covered stories about dogs causing societal issues, and he realized that these issues stemmed from society’s lack of understanding of canine behaviour. He wanted to change that, so in 2015, he left the TV industry and relocated to the US to begin his career in dog training.

Hu adores Bear who he adopted in Missouri in 2015. Bear has been an amazing training buddy and provided constant support ever since. Hu and his wife have traveled across North America always with Bear by their side.

Hu instructs group classes and provides 1-on-1 private lessons focused on dogs with fear, anxiety, and aggression issues.
