Almost from the moment Tans were discovered in the late 1800s from a wild colony of rabbits in England, their development and domestication began. The black Tan was the primary color though the blues followed soon after. The original Tans bore little resemblance to the lithe, longer limbed and sleek animals we know today; rather they were a cobby style animal more resembling a Dutch. Today’s Tans are a highly competitive breed with many enthusiastic exhibitors. – Maximum weight 5.5 lbs.
