Hownd’s Hero Bowl has built-in smart silver-ion technology, which provides the bowl with 24-hour antimicrobial protection. Because the bowl is coated with smart silver ions, it immediately eliminates microbes from coming back after washing. The coating resists bacteria for 25 years, even if scratched or chewed. The bowl, which is made from recyclable polypropylene, has a nonslip base and ergonomic design. It is stain and odor resistant as well as dishwasher safe. The bowl is available in two sizes: small (1.9 cups) and large (4.2 cups).
