Human shampoo
is not much better, and as much as it sounds backward, the better the human shampoo, the worse it can be for your Pomeranian.
The skin and hair of a human, and the skin and fur of a dog have different pH balance. Humans have a slightly acidic pH, fluctuating between 4.5 and 5.5. Therefore, most shampoos are made to meet that need.
But, canines are have more delicate skin; they are very close to a neutral pH, and have significantly more alkaline than humans. They need a pH shampoo and coat products with a pH of close to 7.
With any sort of wrong shampoo and bathing products, this can damage the coat, leaving hairs essentially raw. It is then vulnerable to the sun, the wind, dry air, cold air, static, and contact damage. This can all lead to damaged, dry, brittle hair and/or split ends.
Once damaged fur has a split end, it will run up the length of the shaft.
It will then either break off as it travels up or the fur will snap off at the root. The coat will not only look dry, it will also have clearly visible frizzed fur.
