How often should I bath my Pomeranian? A pet Pomeranian should be bathed on a regular basis. Once a month, during the winter months and more often during summer. The Dochlaggie Pomeranians are bathed twice weekly whilst being shown. The day prior to a show, and once again the day following the show to remove any grooming products added to the coat at the show. Sorry the complete article is only available to our Premium members.
