Be sure to keep up on your schedule of giving your Pom a bath every 3 weeks. Especially in the winter you will want to stay right on track since your Pom's skin will be very vulnerable to becoming dry.
The goal will be to use a moisturizing shampoo to clean off all residue - be sure to scrub down through the coat very well and rinse super well since any dry soap particles will be more irritating to a Pomeranian's skin in the winter. This is followed by using a moisturizing conditioner to protect and soften.
These thorough baths will wash out all the built up oils and products on the fur, leaving it 'fresh' to start over again until it is bath-time in another 3 weeks.
If your Pom has developed very
dry winter skin that is itching, chapped, and/or irritated, you may want to opt for an intense oatmeal based shampoo specifically for dry skin.
With skin so prone to becoming dry in the winter, it is best to allow your Pomeranian to air dry and refrain from using a blow dryer. Use a soft, absorbent towel and scrunch the coat to absorb water, making sure not to rub.
Plan baths well in advance so that your Pom does not need to be taken outside with damp fur (this could prove dangerous in the winter).
As always, even if you have placed cotton in the ears to prevent water from entering the outer canal, be sure to wipe the leather dry with clean, sterile piece of gauze or a clean, sterile cotton ball.
