Understand what your dog may be communicating through body language, posture, facial expression, movement, sound and context. DogTells helps you slow the moment down and look at the whole dog before reaching a conclusion. Submit a photo or short video and receive a structured, AI-assisted report on the signals in front of you. DogTells is powered by the Board of Canine Behaviorists. ANALYZE YOUR DOG Submit a photo or a video of up to 20 seconds. The report sets out the observed signals, what they may suggest in context, arousal and comfort levels, how confident the reading is, any safety considerations, and what to monitor next. For video, sound such as barking, whining and growling is considered as well. LISTEN TO THE REPORT Hear a short spoken summary of each report in a choice of 6 voices. 12 LANGUAGES Use the app and receive reports in English, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Turkish, Japanese, Korean or Chinese. A FULL CURRICULUM, FREE Eight modules and 43 lectures take you from the foundations of signal reading through facial signals, tail signals, posture, affective states, vocalization, social behavior and safety. Each lecture includes knowledge checks with a rationale for every answer. ASSESSMENTS Test your reading with case reviews of real photographs, timed rapid recall, observation versus inference, and clinical scenarios. A new daily assessment is available each day. RESEARCH LIBRARY Read plain-language summaries of 27 peer-reviewed studies on canine communication, each with its method, finding and practical implication, and a reference of 45 defined signals.

Verdict
The clearest difference is in-app purchases: CATALYST for Learning at none against DogTells's 6. CATALYST for Learning also leads on iOS requirement (10.0 vs 15.1). DogTells's advantage is update cadence (fortnightly vs every 48 months). On price, ads and device support there is nothing between them.
