We use the Outward Hound Slow Feeder XS with Bronx. It is really small and works perfectly for him.
We also highly recommend Nina Ottosson food puzzles! Our trainer suggested not using bowls for feeding Bronx so we also use a treat dispensing ball (roll it around and his food falls out). We also like to use muffin tins and just fill each section with a little bit of dry food and it slows him down as well.
Here is the bowl we use:

And this is the food ball we use for him:
