Traditional hangover cure.

Before the days of paracetamol, a traditional rumoured cure for a hangover was to put a small amount of dogs hair (or a whole dog) to your nose.

The pheromones given off by canines were said to help alleviate dry mouth and headaches caused by excessive home distilled gin and other strong alcoholic drinks

Any alcoholic beverage, the consumption of which is supposed to clear up one's hangover from previous drinking (but will tend to have the opposite effect in reality). Origins of the phrase date back to medieval times, when hairs from a biting dog were put in the bite wound in the belief that this promoted healing.

Means that something is very fine, or that you feel excellent. If someone asks how you feel and you simply say "fine", you might just be saying it out of convention. Adding the "dog's hair split three ways" shows that you actually mean it.

Another form of the expression is "finer than a frog's hair split three ways", although literal frogs do not have hair.
