From a roll of flag bunting, cut 1 strip of 2 flags. Repeat so you have two 2-flag strips.
Fold each strip in half. Position them so that the open ends are facing each other and one is a mirror image of the other.
Place them so that the open ends overlap 1/2 inch to 1 inch. (If your dog is on the smaller side, you can overlap a little more.) Using hot glue, attach the ends together. Let glue set.
Pinch the middle where the two flags meet. Apply a dab of hot glue to secure the fold.
Cut a 3-inch length of the red-and-white-striped ribbon. Place the bow tie on a dog collar, and then place the ribbon so that you can create a loop around the middle of the bow tie and the collar. Apply a dab of hot glue to 1 end of the ribbon, and secure the loop by attaching the ribbon to itself. Avoid attaching to the collar. Let glue set.
When fitting your dog, adjust the position of the bow tie by sliding it.
