Yikes.. last two replies are kind of harsh.

I'd say let the girl feed the dog. She could set the bowl down.. or feed the dog a kibble at a time. The dog should realize that they're below the child in the chain of command. And the dog would also associate the girl with food ( a positive), thus making it like her.

NONE of my dogs.. even the two we recently added.. have issues with me taking their dish once they've started eating. That is definitely something that should be worked on, as it is inevitable that they've be in the same room at the same time.
