We recommend bathing your puppy with baby shampoo once a week until it is completely housetrained. Clean puppies seem to housetrain faster. If your puppy gets dirty between baths, you can stick them in a sink or tub and rinse off the dirt without using shampoo. Anytime you bath, avoid getting soap/water in ears and nose. Rinse well to remove all the soapy residue. Soap strips the coat of oils that help keep it shiny and soft. Soap also dries out the skin so bath no more than weekly as a pup and as needed when they are adults.
