When I'm bringing my dog along for an errand, I often scoop him up before we go into a store. It's a habit from our time in NYC where people do tote (read: sneak) their dogs in just about anywhere, and I continue it even if I see other leashed dogs walking around mostly for my own peace of mind that he's less noticeable that way.

If you have a pup that is small enough to be carried (or hidden in a bag), do you think that lifting those paws off the ground makes any difference than walking him in on all fours?
