Slow feeder advice

I adopted my first fully brachycephalic dog in December. I use a slow bowl for my basset but his face is so flat I’m not sure he could use similar type as what my basset does. I’d also prefer something plastic or silicone as they get wet food with their dry frequently. Anyone have good suggestions? There’s so many types and lots of them are puzzles, I don’t think I need that. I just wanna slow him down some cus he gets hiccups after every meal.

Y'all think this product is defective?

My beautiful boy was 4 yesterday.

This is Neville and he’s the best boy.
