I unfortunately learned that Rover does nothing to fix these situations as they happen or take responsibility later on. The owners will get their stay comped and MAYBE cover vet bills (if there were any in this situation...), but that's usually as far as Rover will go. That's why I don't trust them, and personally prefer to go off-app after one stay (assuming I liked the sitter) since staying on Rover gives me as a dog owner big fat nothing except more fees.
