Growing up in North Bay, Ontario, Canada, Sara Carson successfully ran her own dog training business for over five years. During that time period, she taught dog trick classes, obedience, puppy foundation, and agility. Currently, she is traveling North America and spending her days performing with a popular stunt dog team.
Carson is considered one of the top trick dog instructors in the world and is certified through "Do More With Your Dog!" She has taught numerous free online trick classes via social media for the past few years. She has earned several agility titles and also enjoys competing in Dock Diving, Frisbee, and Canine Freestyle.
Known for her appearance on The Late Show with David Letterman, Carson and Hero have captivated audiences all over the world. They have also been seen together on The Marilyn Dennis Show, CTV news, Rogers Daytime Toronto, and multiple live shows such as The Canadian Pet Expo, Purina National Dog Show, and the All About Pets Show. Carson skillfully trained Hero to take part in several commercials for Petco, the Family Channel, and the Pet Network, among others. 
Hero is a Border Collie that grew up in Ontario, Canada, but is currently traveling the USA with Sara. Starting at the young age of 4 months old, Hero became the world's youngest champion trick dog. He knew over 60 tricks back then and currently knows hundreds.
