The bandanna is so easy to make. For a lab/retriever size dog, cut a square of fabric that is 25 inches by 25 inches. Cut the square into a triangle by cutting a diagonal line from one corner to the opposite corner. Fold a quarter inch of fabric under on each of the three sides and press with your iron. Then sew with an 1/8 inch seam all the way around. And you're done! Pretty easy right? All you have to do now is get your dog to sit still long enough to put it on him.
I think he looks pretty handsome with it on. But I'm a bit partial to this little guy!
