With an impressive coat, the collie gives off a regal air, but they’re working dogs through and through. The breed is especially fond of children, so much so that it has been characterized as such in TV and movies — remember “Lassie”?
These smart, athletic dogs love constant companionship and exercise. Make sure to groom them frequently, too.
