I was worried about trusting my dog to strangers but it wasn't too bad with Wag. Overall most of the people were decent but I'd occasionally get some really bad walkers who wouldn't fill out the report card, or walk the dog for 90 minutes instead of 30. My partner and I decided doggie daycare was the better bet. About $35 a day to have our dog just hanging out with other pups is worth it...especially when the quality of walker is so variable with services like Wag.
