There's a MailBoxes, Etc. near home that has a resident Yorkie. A tiny little thing ... she has a bed on the counter. Whenever anyone comes in the store, she trots to the end of the counter to say Hello. She's spoiled rotten.
You have a tanning salon; do you have a health code you need to adhere to? That may prevent you from taking the pup to work with you.
I work by myself most of the time, and there's very little walk-in traffic (deliveries, mostly). I can lock the door and make them knock, or I can put a gate across the entry. But I don't bring the pups with me. I don't/can't bring both of them, and the one that didn't go would really pine for the other. So they both stay at home to keep each other company - and to greet me exuberantly when I walk in the door
.
I miss them, but if they started barking when I was on the phone, I'd have a lot to explain.
