Hi, this is Susan Moore or My Otis I read about your article on removing eye stains on Bulldogs, How long do you leave the mixture on the stains after you apply it to your Bulldog? Thank You, Do your Bulldogs have a doggie door to go outside? Is it good to crate them when I am not home? How often do you bathe your Bulldogs? How often do you clean their paws? Thank You, Susan Moore
