Whether used on hot days or every day, this clever cooling dog bowl ensures your dog's food and water remain cool and fresh all day long. The secret is the freezable core (filled with non-toxic gel), which is housed beneath the bowl. Two cores are included, so you'll always have one at the ready. The stainless steel cooling dog bowl features a non-skid bottom and a small external reservoir which, when filled with water, helps prevent crawling insects from reaching your dog's food and water.
