Bath brushes are excellent and if you want to make your grooming routine even better, I recommend to start using one. Bath brushes are soft rubber comb style brushes that are made for use when wet. I recommend shampooing first, then begin work with the bath brush after. This way, the shampoo can sit in the coat for longer and the brush will effectively massage the shampoo into his skin and coat. This is a highly reviewed bath brush on Amazon.
