PleaseFrom what I hear, you’re not supposed to constantly change up your dog’s diet.  This makes me feel sorry for dogs, because they have to eat the same thing every day.  But then I think, “Did the people who played the munchkins in The Wizard of Oz play multiple roles?  Or did they really have one actor per munchkin role?  I mean, they were in such extreme makeup and costume, nobody would notice if it was just a few munchkins, but in different costumes at different parts of the march down the Yellow Brick Road to look like a larger group.”  And then I realize that it’s a sad, sad world we live in that dogs’ diets are overshadowed by a movie.  Toto would be sad, folks.  Sad, and bored with his meal.
