An undercoat rake is a great tool to use once a week to gently comb out loose fur. The rake can often release small matts and tangles as well as removing undercoat if used gently. The hooks on the rake are designed to always be used with the flow of the coat and can cut if used incorreclty so always use after consultation with your groomer. However, its correct use enables it to be a fantastic tool to help your dog have excess hair removed, helping to maintaintain the coat for longer in between grooms and avouid tangle prone fur.
