Shelties usually live between 12 to 15 years, and some live even longer. Taking good care of a Sheltie may increase its lifespan. Feeding the dog quality food, making sure that it gets plenty of exercise and taking it to regular vet visits increases the overall health of the Sheltie.
Shelties are active dogs and should get 30 to 60 minutes of exercise daily. The name Sheltie is a nickname for the Shetland Sheepdog, a herding dog from the Shetland Islands off the coast of Scotland. Shelties can be sable, black and blue merle in color. They generally stand 13 to 16 inches tall and weigh between 15 to 23 pounds.
