Dogs and tennis balls just go together like genies and mutts do not go together. Just ask the exasperated purple lamp-dweller on the front of the colorful, clever, canine-focused Birthday cards for sale here. The life-altering vaporous apparition just can't get the value of having three "different" wishes across to the cute, playful, panting pup who rubbed up against him. Whatever the ages of your friends, relatives and workmates celebrating a B-Day, and whether they happen to be hound-housers or not, they'll love receiving one of the three cards from this one-design pack in funny, furry and fetching honor of their big birth anniversary.
