Real citation: "Last night, while walking through the historic district, I saw a man exit a building with two enormous Great Danes on leashes. They were a soft charcoal color and one was relatively tall and thick, while the other was smaller and thinner. My dogdar went off and I immediately picked up my pace in order to catch up with them because if there's one thing I love to do while walking, it's stopping to roll around with any given canine; the droolier the better."

Made-up citation: "I hope my dogdar is solid and true, because my biological clock is ticking like a movie bomb clock for a dog."
