The Collie grew out of Scottish sheep-herding dogs and was refined in Victorian Britain, where Queen Victoria's fondness for the breed helped make it fashionable. Lassie later turned the Rough Collie into an American icon. The AKC recognizes two varieties under one standard: the Rough, with a long mane and frill, and the Smooth, with a short, flat coat. Both have a dense double coat and come in sable and white, tricolor, blue merle or white.
Most Collies weigh 50 to 75 pounds, are sensitive and eager to please, and respond best to gentle, reward-based training. Herding instincts can show up as circling or nudging at running children. Many are reserved with strangers without being aggressive. In a Texas city, the coat is the main care item: plan on regular brushing, never shave the double coat, and keep a cool indoor spot available.
