When Fur Does Not Grow Back
When a Pom has health issues which causes the fur to fall out or to thin; there is always a chance that the fur will not grow back as expected. This is called post loss alopecia and for this breed, the reason for this could be the rare BSD.
Studies are currently being done to understand alopecia further. However, as of now, it is thought that there are certain changes that take place in the dog's skin because of the temperature changes that occur when the fur is gone or very thin. When this happens, it can take up to 24 months for the Pomeranian's fur to grow back; though with some dogs the coat will never fully grown back. There has been some promising results in using Melatonin to help stimulate the hair follicles. You may wish to discuss the possibility of this with your dog's veterinarian.
