Waterdog or "dog in water", we have to either put that pipe in water or put water inside it.

SO here goes the two way of how to use waterdog pipe,, we put the water inside the pipe, and now the pipe work like handhold bubbler,

the two ways of use it.

There is also many design that is almost close to a waterdog pipe, make sure your pipe the two chamber are not too close, there is distance that you can place it in a mug,  also there is no really need to get waterdog with leg or little feets
