Their customer-favorite Boomer™ Dog Bowl now comes in a smaller pawprint. This four- cup bowl is built for the smaller adventure companions who still require the same rugged durability and smart, non-slip design. As for you, we made sure it's dishwasher safe and engineered with double-wall, non-insulated stainless steel so it's just as durable, easy to clean, and resistant to rust and roughhousing.
