Butter is a wonderful thing.
Pup covered in sap - rub sap with butter, comb through, wipe off. Sap gone.
Pup needs to take antibiotics, and manages to avoid the pill that was stuffed inside a piece of hotdog (but eats the hotdog anyway) and does this four times in a row. Avoid pill, eat hotdog. ... Next attempt: grind pill, mix with a bit of butter, let pup lick spoon, and voila, pill gone.
