Growing up, we sometimes let the dogs lick a plate after dinner, but it was always brought out the kitchen and put down near their own dish. All our dogs (chronologically Shepherd/Doberman mix, Saint Bernard and Great Dane(3/4)/Lab mix) were all tall enough to eat off the table, but has been trained from puppy hood not to do so. And Freckles particularly liked to "clean" the cereal bowls when we were done with breakfast. Every dish was then going to be washed, anyway, so there was never any chance of dog saliva remaining behind!

With Miss Hoppy, she had no interest in what I ate, anyway, so with a bunny - not an issue! When I ate salad, I let stuff touch other stuff - the horror!
