Give your dog water wherever you go; with H2O4K9, the lid is the bowl. Protect your dog from over-heating due to dehydration during walks, car trips or running errands. By providing safe water from home or water fountains, you protect your dog from being exposed to waterborne bacteria from untreated water sources. Lakes, streams, and the ocean all have the potential to make your dog ill. H2O4K9 bottles are as easy and convenient to use as human bottles are for you, but made to allow dogs to drink naturally from the trough lid. The simple to use, twist top lid is BPA-free and will not release harmful chemicals into your dogs water. The bottles are made from food-grade stainless steel. The H2O4K9 Dog Water Bottle and Travel Bowl has no hinges or complex parts that can break or rust. The lid has a sturdy, built-in clip loop (carabiner clip not included). H2O4K9 bottles fit in the NEOSLING bottle carrier, standard car and stroller cup holders, backpacks, and bike bottle cages.
