As this card says, everyone needs a four-legged best friend in their life. That's exactly why you should send it on August 26th to celebrate National Dog Day! The owner here looks on at his loyal Lab in the most loving way, and it's pretty clear his four-legged buddy feels the same way. So whether they have one pup or a whole bunch of canine companions, share this sweet greeting with anyone who can't live without their furry friends.
