>So, again. Want to understand a puppy? Notice that the very first thing they do any time they interact with anything of any kind any where, is to sniff it first. So, when your puppy moves his nose towards an object, whether or not he goes and smells it, he's talking about it to you. That's why one of the very first "tricks" I train in a puppy is "touch" where he touches his nose to something -- and if you really understand what I've been saying, then you won't be surprised that the first thing I teach him to to "touch" is the tip of my finger.
So your first inter-species communication is literally "smell my finger"
