Anesthetics will also dramatically affect your dogs coat. I must mention that I have found each Pomeranian may need different treatment to achieve the effect I want. What works with one dog may not give me the desired effect with another or what I found worked last year, or even last month may no longer gives me the same results. I bath all my Pomeranians on a regular basis,show dogs weekly,the whole kennel fortnightly during the summer months and at 4 to 6 week intervals during the winter. I have found that clean hair grows and dirty hair breaks off.
Bathing is also helpful in stopping many skin irritations from developing.
As your dog has a different PH level than humans ,use a shampoo that is specially formulated for dogs. I get the best results from bathing my show dogs a day or two before a show. If your Pomeranian has the correct harsh standoff coat bathing will not soften the coat. On the other hand if your Pomeranian has a softer textured coat than desired you may achieve better results by bathing 4 to 5 days before the show. It is important to wash your dog often as dirt and dust are very drying and abrasive to a dogs coat.
