The Shetland Sheepdog, often known as the Sheltie and sometimes as the Shetland Collie, is a breed of dog in the pastoral dog group, resembling a miniature Rough Collie. They have a thick double coat that can come in many different colors and patterns. They are vocal dogs, with few health problems and are very good house and family dogs. A sheltie is very protective and good with children if properly socialized with them while it is a puppy. (Source: Wikipedia)
