I just commented that my neighbour and I used to watch each other's dogs for a few hours, here and there. It was always a text, "hey, is it ok if Lexi comes for a visit?" and when I said yes I'd hear from next door "wanna go see Clifford?", his gate open, and then excited snuffling and wriggling at the door. She'd have a lead on, in case we decided to head to the beach. No food. If my guys went to his place, they had leads on, and a baggy of treats to share with Lexi. No food. As soon as I saw the bag of food, I knew what was going on. (Unless it was because OP had a dog too, and it was "hey, doggo doesn't like this. Can you use it?"
