We started on the kitchen counter with a foster dog who turned his nose up at everything, powders included. I had been through two tubs of the usual stuff and both ended up as a dusty ring on the bottom of the bowl, which meant scrubbing it out every night before I had even started dinner. Two weeks in on this one he was clearing the bowl without being asked, and the routine has held since. What I like most is how little fuss there is now at dinner time, nothing to measure and nothing to wash down afterwards. The bowl gets emptied and the floor does not, and after six months that is a trade I will take every day.
