Yellow Manners Cap for Dog Walks Can be attached to an empty plastic bottle for use. Previously, I used a one-touch cap on a plastic bottle, but the opening was too large and too much water came out, making it difficult to use. This one sprays like a shower, so it was comfortable to use. It has a strap hook, so I attach a strap to make it easier to carry.
