What are the typical extra fees to watch for? Do leave your dog there if you go out to dinner or do you always have your dog with you? I’d be afraid mine would chew something, or bark and cry until we returned.
With Airbnb, VRBO and others, there is the stated nightly rate and then, the host has liberty to ad other fees such as cleaning, service, occupancy taxes and other, etc. You usually have to go into the listing to see the extra fees. Most are minimal and/or reasonable. Some are excessive. I like that airbnb shows the total (less Airbnb take) as a sub price on the original listing page.
With pets, it is case by case and you would want to have some dialog with the host. I think it would be unusual to expect to leave a pet unless you have a crate setup or something similar. Our lab is extremely well trained and crate trained. Still, we are very much inclined to take her with us for the day. We have seen (but not used) on rare occasion a set up where the host also offers to pet-sit. If there is any concern that your pet would chew or bark, you have your answer, IMO.
