1. The neon coloring catches a drivers eye from a long distance away.
  2. The large LOST DOG or LOST CAT are then seen as the driver approaches
  3. Once the driver is closer they already know what is lost (dog, cat, rabbit, ferret, etc.) You now want to give them a picture image in their mind of what the lost pet looks like. Use no more than 5 words. (ex. LARGE BROWN HOUND WITH WHITE or SMALLBREED WHITE FLUFFY VERY OLD.) Keep in mind not everyone knows what every breed looks like so you want to give that brief description.
  4. The rest of the info can be smaller print, people will now know what is missing and have an idea. If they need to they can stop and read the rest to get your contact number.
  5. We typically put the 8X11 sheet in a page protector that is affixed to the neon poster board so that it is protected during rain.
Supplies and Instructions for 5+5+55 rule
From: Missing Pet Partnership. "At any typical intersection, you only have five seconds and five words to get your message across to drivers who are passing through the area where your pet is missing." The above link has instructions on how to create an effective poster.

Missing Pet Partnership founder Kat Albrecht shows samples of effective posters, shows how to make them, and the importance of following the "5+5+55 Rule" (and using giant, neon posters with giant sized font lettering) when creating lost pet posters.

From Missing Pet Partnership: "Most pet owners post lost pet FLYERS that are 8 1/2″ X 11″ white pieces of paper and the only message conveyed is REWARD LOST DOG or REWARD LOST CAT. These are too small and very few people passing by even notice these. Even if drivers did manage to see the words “LOST DOG” very few will pull over to read the description of the lost pet. If instead you create a highly visible poster that conveys the message “REWARD LOST DOG–YELLOW LAB” or “REWARD LOST CAT–SIAMESE” or “REWARD LOST DOG–TAN TERRIER RED COLLAR” that every person driving by could quickly read, you will increase your probability of developing leads that will help you find your pet!"
