The traditional origami dog face is usually made without the nose, tongue, or lower jaw. If you had a paper that is white on one side, though, you could easily draw on the tongue and muzzle color. You just need one sheet of square paper for this. To start with, the suggested paper size is at least 15 by 15 centimeters. The more comfortable you get with origami, the smaller you can go. For other very simple origami models, try the loopy origami paper plane diagram, easy origami card stand tutorial, or easy traditional origami turtle instructions.
