I have a golden retriever who can make a giant mess when getting a drink of water, but this bowl has helped to change that.  My dog loves car rides and we typically take him with us for outings.  I have always had to bring a dish and make him get out of the car for a drink because he makes a huge mess.  I couldn't believe what a difference this water bowl made.  The lip on the top really does help to keep him from splashing water everywhere. Now it just runs back into the dish.  The inside of my car stays dry and my dog is happy to not have to jump in and out of the car so many times.  He is a little older and his hips get sore fast so I like to save him from climbing and jumping whenever I can. We have taken a few trips now, and my car has stayed dry through all of them.
