I recently just finished a 6 day booking with Rover. My dog came back smelling like smoke. Had I known I was dealing with a smoker (of what? I'm not sure) I would have chosen another babysitter. We wouldn't leave a human child in a smokers house, why would we subject our cherished pet to it?.... Please add a 'Smoke Free House' icon to each babysitter, so we as customers don't have to ask each sitter this question.
