Eti: While I don't feel qualified to evaluate the whole of your reference material, I mostly got the point. Do you think that the data your dog and mine download from our shoes alters their behavior? Do they ignore us if it appears we've been stepping on each others toes, hide from us if we've been kicking someone who's down, avoid us if we've been climbing ladders, or comfort us if some one claimed us as territory? Sparky just came up and gave me what passes around here for a hug. Sparky doesn't much care what I wear. While she is interested in what I smell like, her main interest seems to be what I have in my hand and what I'm going to do next. Me too. Howsomever! Sweat pants ALL the time? I think there's some marital advice needed here...I'll be glad to send it to you in another 40 or so years when I've got it all figured out.
