I recently bought a clever little dog backpack [k9sportsack.com] and its the funniest thing I've ever worn in public (not counting performances, that stuffs on another level). I've managed a couple trips this week and despite being a bit chilly, I think he really likes it
In his sack he becomes a dog alert system. Whenever his back feet start squirming about there's a 90% chance another dog is afoot, 10% it was just kids.
