The DogIt Anti Gulping Dog Bowl is designed to stop your dog from 'gulping' down his food. Dogs naturally tend to gulp down their food without much chewing, the majority of the process of breaking down their food occurs in the intestines and stomach without the help of extended chewing. This natural tendency can cause stomach upsets in many dogs leading to problems such as bloat. This is particularly true of large breed dogs and of older small and medium dogs. The Hagen Anti Gulp Dog Bowl is designed with ridges that stop your dog from eating too fast by obstructing him. This bowl is also solid and stable so it will stand firm and not get pushed about the place by your enthusiastic eater! A very clever product.
