My dog would times have the issue of coming back from a hike or something, being very hungry and slamming his food only to upset his stomach and vomit shortly after. It wasn't a regular thing for him but enough of an annoyance I wanted to try this out. I can testify it works great and give me a little extra time in the morning to get ready while he eats. Definitely recommend. the two colors are great so I can assign one to each of my dogs and they learned which bowl is theirs based on the color.Our Great Dane pup was eating so fast she made herself sick. This bowl absolutely does slow her down, from 15 seconds to a solid 2 minutes. It's long enough to give her digestive system time to catch up with her. Have thrown it in the dishwasher with no issues. 10/10 would buy again.Sturdy. About as easy to clean as you’d expect. Too deep for my dog (little dog) but would be good for bigger dog. Would recommend.You do need a small headed brush to clean it. However, my puppy can't inhale her food anymore.She’s still crazy about her food, but it has slowed her down a little. My puppy was the runt & evidently had to fight to eat.We love this bowl for both of our chocolate labs. Easy to clean, pretty to look at and durable for their adventurous doggy ways.Works well. Just wish the bottom had more rubber pads to prevent it from sliding all over the floor. The small strips of rubber aren't wide enough or long enough. But does prevent from damaging the floor. It just adds to the puzzle of the bowl I guess ?.I got this bowl because my puppy when she eats out of a regular bowl she swallows the food. She eats super fast so figure this bowl would help her to eat slower and so it did.
