I sneak ZoE into places, if I happen to have her with me & I want to run in somewhere. I keep a KB bag in my car at all times specifically for this reason.
She's always hidden in the bag & usually no one knows she's there...
although, there was the time in Sally's Beauty Supply, when she sneezed & the whole bag shook while I was at the checkout counter, and then there was the time I was doing the self-checkout at Meijer, and as I lifted a pack of lightbulbs out of the cart, one bulb fell out & exploded on the floor and ZoE barked!
