When we were kids we had what was called a 2 second rule in our house. Which was… if you dropped anything edible on the floor and you picked it up in 2 seconds or less you could still eat it. Well needless to say with a pack of dogs and how we feed ….that rule is not an option here.
We feed this way because it prevents fighting for food when they have no bowls to guard. So every day just a simple mop bucket full of bleach water is how I clean this dog bowl. Works great!
