I've let my dog sample every one of my bodily excretions. He seems to like ear wax the best. This probably doesn't need stating but I live alone, except for the dog.
@The4thCircle@fesshole A lot of dogs are coprophilic. My dog was fond of cat shit, which was the species of feces she had the easiest access to in the window of time between when the cat shat and someone cleaned the litter tray.
