When we put food down for both of them, Jada gulps hers down and the Dink runs away. For the next 20 or so minutes, he'll approach it (sometimes) or just walk off, but either way Jada jumps in and starts chowing down. After 20 or so minutes, the Dink will eat and Jada will watch him intently but won't approach: he'll (finally) growl at her if she gets too close.

In every other thing, the Dink seems to be the alpha dog. I think Dingo has an eating disorder!
