A Picky Habit

I broke down and I went to Wal-mart to find some better food. During the Superbowl at the Doyle's, Bubba got a taste of Brutus' food, Beneful. So I bought a small bag for Bubba to try. But instead of changing it all at once, I mixed his old food with his new.
What happened? Bubba starting eating. I thought, "Great!" I went to watch a little bit of TV and let him be with his meal. About an hour later, I went to check on the bowl to see how much he ate.
I walked towards the kitchen to find a trail of food leading into the kitchen from the dining room. Bubba was eating alright. He was eating his new food... and only his new food. He would take a mouthful, drop the bits on the floor, sniff out the Beneful, and then eat piece by piece only the Beneful food.
Oh, my little low maintance, happy-go-lucky-puppy, everybody's-pal, turns out to be a picky eater! Literally.
