12" x 7.5"Beware of Dog Sign. Are you tired of buying those plastic signs at the hardware store that only last 6 months to a year. This is the perfect sign that will last a long time. They are made out Aluminum so they will NEVER rust. We put 2 mounting holes in the sign to make it easy to hang. We paint our signs in automotive paint and with clear coat so they will last out in the weather. We can paint the center in any of our colors we have in stock, just send us a message if you want something other than red.
