These brushes are a true classic among the slickers. Thanks to their eye-catching packaging and their authentic, German design, they have been a popular product for many years now. The Frank’s Universal Standard Medium Slicker has a slightly curved brush pad and can be used for every dog breed that isn’t short-haired. Because of the finer, more flexible pins, this slicker is most suited for the daily and regular maintenance of thinner or long coats that don’t show a lot of tangles. If you have a puppy or an older dog with sensitive skin, it is perfect as well.
