My little 7 mo. old has two dishes against the wall; one for food and one for water. While he leaves the food dish alone, daily (and sometimes more often), he will take his paw and clear out all of the water in his dish all over the floor and then take off with the dish. I'm not sure how to curb this. I don't want to take the water away if he gets thirsty later but at the same time I don't want to keep filling it for him to spill out. I thought of the tall self feeding but that didn't work, he just scoops until that's empty and takes off with the whole container---the little devil! Any suggestions???
