I do dog walking sometimes in spring and summer, but I don't charge. Luckily I have parents who spoil me ! I know a couple of people who do charge and they usually want about £3 an hour, not sure what that is in $s but it's probably 5 like the others have said. Guess my freebies put the chargers out of business....... then again I only do it when I have time and that's not always that often
