I got this for a road trip, wanting to keep water in the bowl between stops (not pouring a new bowl and then dumping it every time). It was great: let the dog out, set the bowl out, then put it back on the floor of the car before setting off again. The water doesn’t spill. However, we used it as the regular bowl during a long visit and then back at home my dog prefers it to her “normal” water bowl. So it’s the new normal, with far less mess. It’s also nice just for carrying between sink and floor- no spills then, either!
