Generally ask about the dog's temperament, activity level, dietary needs/restrictions, and any medical issues. Also ask for the location and phone number of their vet in case of emergencies. Ask the owners to make a schedule of when they usually feed and walk their dog.

We aren't too fancy around here. Walking is a huge deal for me, though, so we do a morning walk five days a week, as that's the most my schedule allows. I'm also a big proponent of enrichment and mental stimulation, so I try to feed with food dispensing toys if possible. Other than that, they chill while I tackle the never ending to-do list! I've only done the dog park thing once or twice, and it was with a dog I really trusted. I do sometimes take adventure walks through different neighborhoods---depends on my schedule and the dog's comfort with car rides. I've also done a few hikes, but again, I'm picky about who I take: leash manners have to be solid and I have to be confident they'll be okay if an off-leash dog comes racing up (especially since trails are generally narrow with no place to give space).
