I have a jack Russel/corgi mix dog that travels with us quite a bit. It’s always a bit of a challenge trying to find both a water source and a bowl at the same time. I bought this water bottle in hopes of resolving that dilemma. I went out of town this weekend, took it with me, and it worked great! I could give her water in the car and at pitstops. It is very simple to use, is watertight, and very convenient. The only thing that is a little bit cumbersome is having to keep pressure on the bottle to keep water in the bowl. Once I realized you can seal the valve at the bottom of the bowl with water in it, we were good to go! Very convenient! Definitely a great find!
