I actually don't feed Moab out of a bowl now at all, partly for this reason. I bought him a Tug-A-Jug and use that instead. Basically, its like an old-fashioned plastic milk bottle with a rope coming out of the neck. The bottom screws off so you can put the kibble in then Moab has to work the rope in order to get the food out.
It now takes him about 20 minutes or more to eat a meal because he's eating only 3-5 pieces per bite. Plus, its interactive so its just another game to him. So far, its stood up to some pretty rough treatment as well. I highly recommend this to anyone that has a dog that eats quickly or that simply wants to provide some additional stimulation.
You can find them on Amazon and several other pet websites. Just google Tug-A-Jug ... you'll find it!
