Introducing The ‘Perfect Pitch’ Piano Dogs

Perfect pitch is one of the most sought after skills that a musician can acquire, some are born with it and some learn it over time, but how jealous would you be if you found out that animals could possess this discernment as well? For the non-musicians, perfect pitch is the 'magical' ability to hear any note and immediately duplicate it on the first try as easily as repeating a familiar word. One woman has trained her dogs Temper and Qurious to hear a pitch and then touch the corresponding key on their doggy piano...

While I'm impressed at the dogs' ability to never miss, I'm curious as to why he (or she) always looks straight ahead (looking for visual cues maybe?), always uses the same paw or doesn't always play back the proper octave (which is impressive in and of itself.) I have to think that the piano playing ability has more to do with associating tones with standing positions rather than recognizing some kind of sight picture like we do. What would REALLY impress me is if the dog was able to vocalize (howl) the notes back in key that were played.
