Dogbnb in more ways than one: You can choose to pay a sitter to put up your dog for x nights, or you can pay someone to LIVE IN YOUR HOUSE and take care of your dog. It makes sense, of course, but sounds a bit odd.
Indeed - I've talked a sitter on Rover who was planning on listing their profile in NYC as a traveling sitter as a way to get a free stay in the city, while also watching someone's home & dog.
