Late-night dog walks. An active dog walker might only have to work a 9 am to 5 pm Monday-Friday schedule. Late-night walks for some dog walkers are premium services. 2. Early morning dog walking. As we know some people are not early morning people. You might have to pay extra if you need someone to come to your home before 7 am. 3. Holiday walks. A regular dog walker doesn't have to work on the holidays as pet sitters do. A dog walker might add a premium for holiday dog walks. 4. Weekend walking. Dog walking is primarily a weekday service and weekend walks might cost extra. 5. You live outside of their service area. You might have to pay extra if your dog walker has to travel far to reach you.
