Variant of obsolete fist, short for fisting dog, from Middle English fisting, a blowing, breaking wind, from Old English fīsting.(American Heritage® Dictionary of the English Language, Fourth Edition)
Earliest sense is “fart”, and later “stink”. Sense of dog is 1805 American English, from earlier forms fice and fist, as abbreviation for fysting curre “stinking cur” (1520s), from Middle English fysten, fisten ("fart, break wind") (mid-15th century) (related to Old English fisting ("stink")). Old English term is from Proto-Germanic *fistiz- (“a fart”), presumably from Proto-Indo-European *pezd-, though this is disputed. (Wiktionary)
