Any good magician worth their salt knows that misdirection is the key to a good trick.
This dog skipped that lesson in magic school.
As it frolics through the bushes, this dog calls attention to itself. "Look at me! Look at me! Nothing to see up my paw!" And then it drops into the bushes, ninja-style, in an attempt to disappear. But the trick doesn't work particularly well without some smoke or another bit of razzle dazzle to distract us from the hiding.
Also, we can see its nose sticking out from bushes.
It's a good first attempt, but the dog will need to work on the trick a bit more if it wants to impress at the next doggy talent show.
