A dog walker walks your dog for a scheduled amount of time, typically on a pre-determined route, to ensure they get sufficient exercise and can go to the bathroom while you are away. Dog walkers dispose of any waste from the walk, make sure your dog is safe and hydrated, and may also feed them upon request.
Most dogs do well with one 20- to 30-minute walk per day. Puppies and more active dogs typically need two or three walks per day and may need longer walks.
