Dog pooping in food bowl?

I haven't moved the location of it but I would say he is targeting it. I have stood off in the distance and actually seen him go to the bowl and smell of it and then turn around and poop right in the bowl. That makes you want to get rid of him but he is has a good nose and is easy to handle so I have put up with it. I will try and moving it to a different location and see if that works or try the rabbit feeder thing. I've seen those feeders at the COOP, are they big enough for a grown dog to get their mouth down there and get to the feed? I'm sure a puppy could use it.
