same here, I have to feed 5 individually, what I do is I mix their foods and fill their bowls in the kitchen, then I put each bowl in their crates and put them in pack order in the crates to eat, and they stay in until all are done, then I put them out in pack order too..
first Harrison Ford, then Prada the yorkie, who eats wellness simple, then Chanel Coco, after that Relay and last but not least the baby, Delilah. I been doing this since the Vet put Miss Prada in Wellness because of her stomach issues.. I know it sounds hard, but I got it down to a science I can feed them in 20 minutes max, then off to the yard they go to do their puppy business and after that they crash in my bed to watch tv....LOL
hugs,
