The same time every day, around 11pm, I go to the kitchen, select two different treats, say the word “choice”, and present the treats in either hand, allowing Bebop to only take one... By the time the experiment started, Bebop was used to the routine and sniffing both treats before taking one.

Winner was Pur Luv Chicken, closely followed by MON2SUN duck + rawhide. Greenies and Pork Chomps fared poorly.
