Odie would do this same thing if we didn't elevate the cat food. In our case, it's definitely not any kind of preference to the cat food. It's because it's the cat's food. I know some people with multiple dogs experience this, even if it's exactly the same food.
You can train her to not touch the cat food, but for us it was just easier to put the cat food on a little platform so they can eat in peace without me hovering around them.
Edit: I was also going to say that it's not the end of the world if she eats some cat food, but there are definitely differences in commercial dog and cat food, because both are balanced for the species it's meant for (ie. cat food has taurine, which is essential for cats but not for dogs).
