Went hunting opening day of dove season, needless to say, mosquitos were angry! Didn't want to use any chemical spray, and don't like putting any more chemicals into Elvis than absolutely required, i.e. heartworm meds. Only thing I had handy was Stink Bomb, a spray dog deodorizer and conditioner. Didn't have it day one, so I knew how bad it would be, but, after using Stink Bomb, the mosquitos didn't bother Elvis at all, and repellent quality seemed to be as good as my Deep Woods Off. It's made by Animology, and I think I bought at Petco. I would recommend for keeping the bugs off Bowser and making him smell good at the same time!!!
