Developed by veterinarian, Dr. Mike Woodrow BVSc (Hons), Oral Health (OH) Bowls bring innovative design to your pet's feeding time. The OH Bowl features raised ridges and nodules that guide the dog into licking up the food in the channel in between. This results in a slowed eating rate. Within the channel rests a uniquely designed bone shaped scraper that cleans the pet's tongue with every lick and reduces bad breath. The non-skid base ensures that the bowl remains in place while the pet is eating.
