Hi, I’m Cara. I’m a life-long learner and creator with a passion for dog training and the science of canine behavior. My love for dogs began at the age of 4 when my first family pet was a black lab named Dallas who was most definitely not trained to do tricks! Since then I have had several dogs ranging from pugs to Dobermans and I have an unreasonable enthusiasm for all things doable or teachable in dog training. After spending several years training dogs and people in a variety of environments, I formally earned my master dog training certificate.
