Rover.com typically does not impose automatic additional fees specifically for last-minute bookings; however, individual pet sitters or dog walkers may set their own pricing structures. These sitters vary in their policies regarding last-minute requests. Some may choose to charge a premium for bookings made with short notice to accommodate the sudden change in their schedule. When using the Rover platform, users can view the pricing details on each sitter's profile. It is also a good practice for users to communicate openly with sitters about their specific policies and any potential additional charges that may apply for urgent bookings. To ensure clarity on any fees associated with last-minute requests, users can refer to their chosen sitter's guidelines and pricing on the Rover.com website.
