New foster lab Rufus is a man who knows his fractions.

He arrived a little underweight, so we decided to push his meals up to two cups morning and night. But when I did that, he only ate two-thirds of what I gave him. So I backed it off to a cup-and-a-half—no need to waste food—and he ate two-thirds of that. He did the same with one cup. Then, being as I am blessed with having the superior brain, I decided to outfox him by upping things to three cups. No good. He still subtracted a third—then subtracted a third again.

Now I’ve changed my strategy completely—using addition instead of subtraction. It’s working too. Because ever since I started adding that generous spoonful of chopped turkey with each meal, I swear he’d lick the sticker off the bowl if one tiny shred got stuck to it.
