After a lot of thought, I came to the conclusion that a dog is something with about four legs (some have fewer), that smells, that poos in the park and chases cats. So far, I haven't managed to get Storm to do any of those things. I therefore felt compelled to vote against the motion that Storm is a dog.
Recently, however, I have been conducting experiments by chasing dogs around the park and effecting a series of blows with my MIDI keyboard. Certain canine responses did sound a bit like Arsenic or Shadow so maybe cindie was right.
Actually, the real dog round here is Brass. If they'd brought Storm up to (say) the sound quality of Reason instead of wasting their resources on a project that is more a scientific curiosity than something with any chance of success as an instrument then maybe we'd have Storm 4 by now and it would have us all purring.
