How much food or water does the Boomer 4 hold?

About 4 cups, roughly a quarter gallon. That suits small and medium dogs; large dogs will need refills or a bigger bowl.

Is it dishwasher safe?

Yes. The stainless steel body can go in the dishwasher, and it also rinses clean by hand.

The wide 6.8-inch base and non-slip ring make it very stable on hard floors. Some owners report the ring loosening over time.

Yes. The steel resists rust and doesn't absorb odors, so it holds up on patios and in the yard better than plastic.

It is heavier, wider-based and less likely to slide, but it holds less than many cheap bowls and costs more. The gain is durability and stability.

No. It is a single bowl; a lid and feeding mat are sold separately.
