Our Safari Dog Flea combs are used to control fleas and identify skin and coat problems. Before using, remove any tangles from the dog's hair. Pay particular attention to areas around the dog's ears, nape of neck and base of tail. Between strokes, dip the flea comb into a cup of water with mild detergent. Our Safari Flea Combs provide a variety of choices to help detect fleas or dry, flaky skin in the early stages.
