Welcome KPCato! my pit Herman eats fast too, so I can relate. Have you tried a “Eat Slow Bowl”? The food bowl is made with large protrusions inside. Duke would have to eat around the the protrusions, thus, in theory at least, Duke would need to eat more slowly. They come in different makes & models, and if I’m not mistaken, metal, safe types of plastic, and even ceramic. Correct me if I’m wrong. I hope this helps.
