Greyhound 16 Month 2014 Calendar. The Greyhound is capable of reaching speeds of 37 mph and is the world's most important speed merchant. The elegant Greyhound is a surprisingly gentle breed which uses speed and sight to overtake prey, be it a living animal or a mechanical rabbit on a dog track! The pet Greyhound is a delightful and relaxed companion, although dogs that have retired have a tendency to chase anything that moves! This is a great Calendar which is sure to delight anyone you is fascinated by this stunning breed.
