Dog Decoder is a canine education and training brand created by Jill Breitner, drawing on her nearly 40 years of study of dog body language. Its app helps people understand what dogs communicate through posture and behavior, including signs of fear, stress, excitement, confidence, and play. Around 60 illustrated poses explain the signals to watch for, such as ear position, tail movement, and head posture, alongside context that helps users avoid common misinterpretations. An interactive quiz reinforces learning, and Diamond, the app’s canine host, guides users through the material.

The brand also offers virtual dog training and mentoring worldwide, private in-home training, and a board-and-train program that accommodates one dog at a time. Jill provides coaching and consulting for canine professionals and offers workshops and presentations for veterinary practices, shelters, rescues, day care centers, and schools. The website’s blog shares practical guidance for families and dog owners on topics including puppies, confidence, stress, and behavior challenges.
