Dog sitting services provide care and supervision for dogs while their owners are away, whether for a few hours, a working day or a longer period. Depending on the arrangement, a sitter may look after a dog in its own home, visit at agreed times, or care for it in the sitter's home. Visits can include feeding, providing fresh water, letting the dog into a garden and giving it company, with overnight stays available from some sitters. Care is usually arranged around the dog's routine and the owner's instructions. This may include walks, play, basic grooming, cleaning up, and giving medication where the sitter is able to do so. Owners and sitters commonly discuss the dog's temperament, exercise needs, diet, health, access arrangements and emergency contacts in advance. Some services focus on one-to-one care, while others look after several dogs, so the setting and level of supervision can vary.
