Perfectly balancing a pile of biscuits on top of his nose, Australian cattle dog Jack could teach circus performers a thing or two.
Showing perfect patience and poise, the three-year-old dog can balance a range of every day items on his face.
In a series of pictures posted on Reddit by his San Franciscan owners Nicole Lee and her boyfriend Trey, Jack is pictured balancing everything from a football to a frying pan on his head.
