Query: Flimsy, small, not for big dogs

The "drinking dish" is a piece of softer plastic that has to be turned inside out, creating KIND OF a bowl.Not worth it. Maybe for the emergency use when there is absolutely no other choice.I will continue bringing a big jug of water and her own dish to the park. My dog is not that big either, 50 or so lbs and the water held there would be enough for oh 1 or 2 drinks.Yes, they do specify 20 oz
