The Collie began as a Scottish sheep-herding dog and was refined in Victorian Britain into the elegant dog people know from Lassie. Rough Collies have the flowing mane and long coat, while Smooth Collies have a short, flat coat, but both are one breed with a dense double coat. Adults usually weigh 50 to 75 pounds, and colors include sable and white, tricolor, blue merle and white.
Many Collies are gentle, sensitive and devoted, and they have a long reputation for patience with children. Herding instincts can show up as barking, circling or nudging at running kids. In Mansfield, plan on heavy seasonal shedding, regular brushing and daily walks, plus a vet who knows about the drug sensitivity common in the breed. Each Collie is different, so meet a dog before deciding.
