Sheltie Unisex T-Shirt – The Shetland Sheepdog, or “Sheltie” as it is commonly called, is essentially a working Collie in miniature. A rough-coated, longhaired working dog, he is alert, intensely loyal and highly trainable and is known as a devoted, docile dog with a keen sense of intelligence and understanding. Agile and sturdy, the Sheltie is one of the most successful obedience breeds, but also excels in agility, herding and conformation. The coat can be black, blue merle or sable, marked with varying amounts of white and/or tan.
