A dog owner has to be very careful about cleanliness in their house, as a dog can be quite a handful to contain. Not only do dogs like to chew up curtains and slippers, but they can also be messy eaters and drinkers. With an elevated bowl, however, your dog is less likely to drip water all over the floor.
Elevated bowls have a space underneath them, so the water that flows there can dry easily. Regular dog dishes, though, lie flat on the floor and will contain the water, causing mold and mildew. Plus, some options for an elevated dog bowl might come with removable dishes that you can wash separately for extra cleanliness.
