The Collie grew out of Scottish sheep-herding dogs and was refined in Victorian Britain into the elegant dog most Americans know from Lassie. Rough Collies have the flowing mane and frill, while Smooth Collies wear a short, dense coat, but both are one breed. Adults usually weigh 50 to 75 pounds, stand 22 to 26 inches tall and live about 12 to 14 years.
Most Collies are gentle, sensitive and devoted, and many are patient with children. They can be reserved with strangers, and herding instinct sometimes shows up as circling, nudging or barking at passing activity, which matters on busy Tacoma streets. Many carry the MDR1 drug sensitivity, so every vet should know the dog is a Collie. Dogs vary, so spend time with a Collie before deciding.
