what is the time frame for the owner to pick up his dog, without getting charge for extra night?

Dog Boarding and House Sitting are both per night, up to 24 hours. So if a client drops off at 9AM, the time runs until 9AM the following day. You as an independent contractor determine if you wish to charge your client for additional time. At the M&G you need to discuss drop off and pick up times with the client, and if necessary make changes to the booking before final acceptance.
