A few questions i would have are any allergies, or medical conditions the dog may suffer from. Any dislikes/discomforts the dog contains, any actions or activities that lead to poor behavior. Alongside this, treat preference, activity preference, the dogs interests, and general behaviors to reinforce (for example if a dog is not allowed on the furniture at home, then said rules should apply at the sitters as well).

There is a large walking trail very close to my residence, it totals four miles. With a safe, man made path that snakes up and down scenic trees and hills providing a scenic and interesting walking experience for both the pet and walker. Activities vary depending on the dogs game preferences. While certain dogs love the comfort of actively laying next to someone others can chase a ball for hours, therefore it's integral to have a conversation with the pet owner.
