The website is dedicated to providing valuable information on dog and puppy training, dog exercise, and feeding a raw diet. Lindsay has over 20 years of professional experience working with dogs and is passionate about dog training.

Writing and dog training are two of Lindsay's greatest passions, and That Mutt combines both of these passions. She is committed to continuous growth in dog training and regularly attends classes and seminars, as well as being a member of NADAC and her local agility club. Lindsay resides in Montana with her husband, where they train for ultramarathons, including the Across the Years Marathon in Arizona.

The blog also features two additional writers, Julia Preston, and Barbara Rivers. Julia Preston joined That Mutt in 2015 and writes about dog behavior and training, working dogs, and life. Barbara Rivers writes about raw dog food, dog training, and life with her rescue dog, Wally.
