Slow your pets roll with a gobblestopper, a simple, elegant solution for relaxed dining. The gobblestoppers help prevent a serious dog health risk: canine bloat. In fact, bloat is reported to be the second leading killer of dogs after cancer. By slowing your pet's eating with gobblestopper, you can avoid gulping of air while dining, thought to be a major cause of bloat. This medium gobblestopper is ideal for bowls less than 6-8 inches in diameter. Its very simple to use; just stick gobblestopper into the bottom center of the bowl using gobblestopper's suction cup. Extremely difficult for your pet to remove, but easy for a pet parent thanks to the easy-lift tab.
