Start by giving puppo treats as you drink a beer. Every time you take a swing puppo gets a treat. This establishes that beer swigs are people treats. Then say "fuck" before you take another drink and then look at puppo and hold out a treat to see if they say "fuck". This teaches them that you get treats for saying "fuck" and if they say fuck they will get a treat. Keep saying "fuck" before each swing of beer and keep offering them a treat but withholding it till they say "fuck."
