Automatic dog feeders?????

Thanks for all the ideas, I think I have figured something out. When I said automatic I ment something outside the pen that you can just poor the amount of food you wanted each dog to have. Should have cleared that up. As far as buying one. I know they sell them at walmart but didn't want to spend that much money and have my dogs be able to eat anytime they wanted.

I have a little boy that is 3 and a girl that is 1 1/2 years old. One of these days I hope they will be more than willng to help take care of the dogs.
