I rinse out the water dishes every day and give them a good wash or through the disahwasher once a week. The dry food bowls I empty of crumbs every day and I wash them once a week. The wet food dishes, I wash in the dishwasher before reusing them. I don't run the dishwasher every day, I have a set of dishes for wet food and when I run through them I run the dishwasher.
