Recent certifications of note include her becoming a Family Paws Parent Educator, and completing Dr. Susan Friedman’s Living and Learning with Animals program.

Rachael loves training dogs! It fills her with joy to see wagging tails and bright eyes as each dog uses their amazing mind to learn all the crazy things we humans want to teach! And it gives her just as much joy to see owners delighted by the discovery that their dogs are such intelligent and fast learners.

Fifteen years ago, Rachael got her start in positive reinforcement training as a volunteer, a mentor and instructor at Sit Happens in Calgary.

Previously, Rachael was the Operations Manager for Rover Achiever Pet Care and she spent six years walking groups of dogs in some of the most beautiful parks in the city. She has a Conservatory Bachelor of Arts from the University of Alberta.

Hu Wang graduated from the Karen Pryor Academy for Animal Training and Behavior under Laurie Luck in 2016.

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.

Erin Britton, CPDT-KA, KPA CTP

Erin has been instructing at When Hounds Fly since 2018, starting as a part-time instructor while she ran her dog walking business, A Couple of Mutts, and moved to full time in 2020.

Before she became a dog training instructor, she completed her Concurrent Bachelors of General Science and Education, and puts her teaching and training skills to good use in the canine classroom. She loves making people think like their dog in order to deepen their understanding of the canine life, and strives to make the classroom a fun and engaging experience for both human and dog learners.

A client’s dog, suffering from severe anxiety and OCD prompted Erin to take a strong interest in canine behaviour. Since then, she’s endlessly studied canine behaviour and psychology in order to help more dog owners truly understand what their dogs are trying to tell them.

Erin lives with her Australian Shepherd Dill, and her calico cat Fennel. Trick training and hiking are their favourite past-times!

Erin instructs group classes and provides 1-on-1 private lessons focused on dogs with separation anxiety as well as fear, anxiety, and aggression issues.

Praise for Erin from the classroom:

“Erin was great at telling us not only what to do but why we were doing it.”
“Erin’s so good with the puppies AND the people. Excellent instructions – no time wasted, very clear direction.”
“Erin was absolutely lovely and a great instructor. She made us both feel comfortable and gave us the confidence we needed to work through this training.”

Mayra Morales, CPDT-KA

Mayra joined the instructor team at When Hounds Fly in January 2021, after completing our intensive Dog Trainer Internship program in Fall 2020.

Originally from Venezuela, she has had dogs and cats since she can remember, so her love for animals started at an early age. She moved to Canada in 2009 to get a post grad certificate in television and Film and pursue a career in this area, which she accomplished.

In 2016, she became a dog parent to a Chocolate Labrador Retriever puppy, Mocha, and took the Puppy Socialization classes at When Hounds Fly. Shortly after, she moved to Vancouver, BC to continue career opportunities, where Mocha started displaying reactivity around bicycles, kids, skateboards, and dogs.

Mayra felt very overwhelmed and stressed about this situation and looked into getting private lessons with a local R+ trainer. After the first session and implementing the exercises, there was such a great change in Mocha that Mayra knew this is what she wanted to do next, helping people like her with their struggles with their dogs and solidifying the relationship between dogs and their guardians.

In 2018, Mayra got her Dog Behavior & Training Certification Level 1 at the International Academy of Canine Trainers in Delta, BC and returned to Toronto in 2019. Shortly thereafter, she started the internship program with When Hounds Fly.

Before immigrating to Canada, Mayra got her bachelor’s degree in communications from Universidad Catolica Andres Bello in Caracas, Venezuela.

She has had a fondness for animals since she was a little girl, with a special love for dogs. She became a dog parent in 2018 when she brought home Bentley, her French Bulldog, who she often refers to as her best friend and greatest teacher!

Her passion for dog training began when working through the challenges she faced with her own dog’s reactivity and anxiety. After attending training with various trainers without much success, she took private lessons at When Hounds Fly, and noticed the immediate difference in service and care. She knew right away that she wanted to help other dog guardians who may be struggling with their furry friends.
