The two-color corgi has black hair on its back. This is not necessarily a sign of strings. It may be caused by genetic problems or other reasons. Corgi's genetic factors include part of the black hair gene. Due to the role of melanin, melanin secretion is relatively strong, which will cause some of the hair to turn black. As it grows, its hair will gradually fade and melanin secretion will also decrease, so it is normal for Corgi's hair to turn black when he was young.
If the black mixed hairs on the dog's body continue to grow and spread, and there are obvious abnormalities, it is recommended to promptly Take them to a veterinarian for a checkup. Some health problems, such as fungal infections, can also cause dogs to develop abnormal black hair.
