My dog, Izzy, was bored a few weeks ago when I was trying to get some school work done. I had given her a Nylabone treat but that took her 3 minutes to eat. Then I played fetch with her and her duck, I held on to one end of her pull rope and I took her outside to check for rabbits and snakes. But I really needed to get some work done so I grabbed a plastic butter container with a lid from the recycle bin. I put some of her dog food from her bowl into it and shook it like a toy. She grabbed it out of my hand and ran off it to the living room where she eats her treats. She threw it on the floor, she batted it around, then she picked it up and laid down on the floor and put it between her paws. She worked at getting the container open and when she did she happily ate her food. I've done this with her food a couple of more times since and now she won't eat her food out of her regular food dish because she likes the container game better.
Lesson learned: Dogs and people like games.
