The Shetlan Sheepdog, also known as the Sheltie, has been intentionally bred small. Shelties are ideally suited for the terrain of the Shetland Islands in Scotland. While they resemble a rough Collie in miniature, they are not a true miniature Collie, as there are many differences in appearance. Shelties are intelligent, family oriented dogs, that can live in an apartment or in the country. They have a thick, double coat that can come in many different colors and patterns. They are vocal dogs, with few health problems, such as hip dysplasia and thyroid problems.
