Works like the standard camera app, but when a dog comes into view, it will get a yellow frame. If you press the white button then to take a snapshot, the dog's breed is printed on the the image before it is saved to the gallery. The app uses a neural network to determine the breed, and it gets right most of the time, but not always.

There is also a button which takes you to the Wikipedia page for the breed.
