The KONG trek & Treat is a premium double walled kitchen grade stainless steel container to keep your dogs water cooler for longer (10z /295ml) and also has a neat little container for treats or a small amount of food on the go. When you want to give your dog water you can either poor into the bowl or simply remove the attached leak-proof bung in the integrated drinker, hold the bottle at 90 degrees and fill the drinker – when your dog has had enough water simply hold upright and unused water will drain back into the container. The beautifully designed and sleek product is BPA free and carries a 5 year warranty.
