Seriouly they know before your do! Black raised lettering reading "No need to knock, we know you're here, -The Dogs-" sits on a backdrop of stained wood (see stain options-Weathered White is shown) This sign makes for a great door hanger, add it to a door wreath or mount it above your doorbell. Please let me know if you only have one dog and I can adjust the sign. As this is a custom design please allow 5-7 days for staining, painting and drying time prior to shipping.
