Hello @Libby2019 and first of all congratulations on getting your first sit. This is a good question and one that you’ll find varies depending on a number of factors including the complexity of pet routines and things you may need to know about the property (is it straightforward or an off-grid remote location for instance).
We personally always prefer an overnight stay and particularly where dogs are involved, as it provides the opportunity to be part of the routine before the owners leave, perhaps go for a walk together, and generally be accepted into the pet’s environment. You’ll get some good and alternative feedback from other members here on which to make your decision, but for the future this is a good topic to include in pre-sit conversations… “how do you like to handle the handover?”.
We’ve developed lots of ways to ensure we don’t become intrusive on a handover… like offering to take the dogs for a walk, or getting settled and agreeing to meetup for the meal (which has always been offered). We show understanding for their packing, and any necessary early nights. That sort of thing. Handovers like this are a great way to form wonderful friendships, we’ve found, and get the sit off to a very good friendly start!
Here’s another thread on a similar topic that you might find interesting to read and contribute to:
