The Shetland Sheepdog is an outstanding companion dog and is intensely loyal. It is lively, intelligent, trainable, and willing to please and obey. Shelties are loving, loyal, and affectionate with their family, but are naturally aloof with strangers; for this reason Shelties must be socialised. Shelties do well with children if they are reared with them from an early age; however, their small size makes it easy for a child to accidentally injure them, so supervision is necessary. Exercise caution when considering an adult Sheltie for a family with young children; they may not be compatible.
