Is the BEST thing I have ever bought for my dogs! (well, becides the Furminator of course haha). Kai's speedy eating has changed dramatically all in one day! He went from eating an entire cup of food in like 30 seconds, to taking well over a few minutes to eat. The first time he tried it he was sliding all over the floor trying to get at his food, he took a second to look at it, then tried again, this time trying to smash his face inbetween the bumps. It was SO funny! I plan on taking pictures next time he eats. He thinks it's a game now, which is fabulous by me, it makes feeding time fun for him! If anyone has the same problem that I did of dogs eating too fast, I would DEFINATELY 100% recommend this bowl. I got mine off of Amazon.com for $15! Cheaper than buying it from a pet website.
