I didn't know Bed, Bath and Beyond was dog friendly... I'll have to go next time! The only places I've taken M/Z is Home Depot and Lowe's. (And of course, pet stores.) I believe their policy says "no dogs allowed other than service dog", but I believe the employee(s) won't ask you to leave unless another customer complains.
I won't take them to anywhere that has food (unless it's a restaurant which has outside seating and allows dogs.). And if it's a HD/L that I haven't been to before, I ask an employee if it's okay to bring them in with me.
It's usually a good experience b/c most ppl either don't mind or love seeing them but I have come across few... rude ppl that made unnecessary comment or gives me (us) that "she's one of those ppl..." look that makes me want to punch them.. LOL
The most recent one was where a woman says to her husband "I don't know why they allow dogs in here, a lot of ppl are allergic to dogs..", while walking past me. (We were at Lowe's)
Magnus is on a 6' leash while Princess Zoey is carried in the doggie backpack. She won't come out of the car unless I show her the backpack and assure her she doesn't have to walk. LOL
