Do you know how to read your dog’s body language? Do you understand when he tries to tell you he’s stressed, or submissive, or ready for fun-time? Can you tell the difference between excitement and fear, or between aggression and the need to play?

Dog language can be confusing, but with the help of Dog Decoder, you’ll understand your dog’s signals like a pro.

Dog Decoder will teach you everything you need to know about how your dog communicates, so you can not only avoid bites, but share in a more satisfying, healthy, and loving relationship.

=== MEET “DIAMOND” ===

Diamond is your tour guide and trainer. He will show you how he looks when he’s afraid, when he’s stressed, when he’s just about to bite, and when he wants to play.


There are about SIXTY different poses on display in Dog Decoder. Each pose is beautifully and expressively illustrated by one of the world’s top dog artists.

Each pose comes with a diagram, pointing out where on Diamond’s body he’s indicating how he’s feeling. For example, in the poses for “fear,” the diagram will point out Diamond’s tucked tail, his ears pulled back, etc. We won’t just show you a picture of a scared dog — we’ll teach you what to look for, the signs of fear.

Each pose also comes with a helpful description of the context. This is where you will learn about some common misconceptions, or what kinds of situations will cause your dog to assume each posture.


The best way to see how much you’ve learned is to take the quiz! Some of the quiz questions are pretty challenging. Diamond wants to make sure you don’t get fooled next time he’s hiding under the coffee table or drooling – will you recognize the early warning signs of stress? Will you be able to warn your children when your dog is clearly done playing?

Excellent app! Only ONE criticism...

This is a REALLY great resource for getting to know what your dog is communicating through body language. My ONLY complaint: I wish the app wouldn't default back to the top after I exit a pose. This gets annoying when I'm reviewing postures near the end of the list. It should default back to the top of the section you're looking at perhaps? Other than that, I recommend this app.

Great App to teach people and children

400,000 children are sent to the ER because people don’t recognize the dog’s warning and stress signals.
As holistic dog trainer and behaviorist, it’s my priority to help people better communicate with their dog’s.
This app is what I recommend to my clients to test their skills and teach their children.
The quiz is a great way to learn safely and build a strong family bond with their dog.

This app has helped a lot in understanding my dogs. One of my dogs sometimes uses tongue flicks and yawns to indicate calm: she'll get on my lap facing me, make eye contact with me, flick her tongue & yawn, then settle.
It would be helpful if after clicking on a picture for details, exiting took me back to where I was instead of to the start.
