"A hair of the dog that bit you" is a phrase used (like you didn't know) meaning "to take an alcoholic drink in the morning after having 'one too many' the evening before". I liken the idea to: if a deep sea diver surfaces too fast he might go back down and surface a little slower to releive "the bends" - or - that a marathon runner, upon finishing a race, isn't supposed to just stop and take a nap. It is safer(?) to cool down gradually. 'nuf said about all that.

Why a hair?

Any other cannine quips?
