A full brother and identical twin to Cosmo, Rusty is also his brother. While Comet (12 years old) and Cosmo look absolutely identical their personalities are very different. Comet, while loving to have fun is more serious than his twin. Comet runs everywhere, lead, wheel & point and loves every second of it! When out in the exercise yard he will usually be the one instigating and leading a full out game of chase. Comet is in amazing shape for his age and still enjoys going out on our 2 hour tours and visiting resorts.
