I have been using the new DOGMA Slow Feed Bowl on all eight of my own dogs with great success. The competition at feeding time, which is twice a day is extremely intense and food gets gobbled up in no time. The first finished runs to the slower feeders and harrasses them. Gagging and laryngeal spasms had been a common phenomena. Since using the DOGMA Slow Feed Bowl mealtime is a pleasure. They finish their meals MUCH slower and more equally, so no altercations between dogs. Also no more gagging and laryngeal spasms. What a pleasure. It is so much healthier to eat slower, chew their food for longer, breaking it into smaller pieces – referred to as mastication- and consequently promote better digestion thereof, just as it works for us!
