Your Pomeranian's fluffy appearance is the result of a soft, thick undercoat beneath a straight, coarse outer coat. Without regular brushing, the downlike undercoat will tangle easily, eventually ensnaring sections of the outer coat and leading to a nasty mat that can aggravate your Pomeranian's skin.
Step 1
Mix 1 part dog conditioner with 2 parts water in a spray bottle. Part your Pomeranian's coat until you've isolated the knotted section and apply a single spray of diluted conditioner to the snarled hair. Misting the knot with a lubricating, protective substance like dog conditioner makes it easier for the brush to separate knotted fur.
Step 2
Brush the lower half of the knot, furthest from your Pom's skin, using a slicker brush and short gentle strokes. Move closer to the skin once you can easily brush through the first section of the knot. Unlike a traditional comb, which forces the knotted fur through a single row of teeth, a slicker brush's dozens of needles will penetrate and loosen the knotted hair in several different places.
Step 3
Repeat steps 1 and 3 until the brush flows smoothly through the entire section of hair. If your Pomeranian has several knots in his coat, secure the sections you've already untangled with a small hairpin so you know which areas you've already treated.
