Sheltie vs Collie: Is a Sheltie Just a Mini Collie?

Side by side

Size: the AKC lists Shetland Sheepdogs at 13 to 16 inches and 15 to 25 pounds, and Collie males at 24 to 26 inches and 60 to 75 pounds, females at 22 to 24 inches and 50 to 65. Lifespan: 12 to 14 years for both, per the AKC. Popularity: the Sheltie ranks 29th and the Collie 39th. Coat: Shelties have a long, harsh coat over a dense undercoat; Collies come in rough, long-coated, and smooth, short-coated varieties.

Energy: both are moderate. VCA says a Collie needs a long walk, good run or energetic play daily, and a Sheltie a long walk, short run or backyard games. Barking: VCA rates Shelties 5 out of 5 and Collies 4. Training: both rated 5 out of 5 for ease of training. Children: both excellent. Strangers: Collies are friendlier; Shelties can be aloof or shy. Best for: Shelties suit smaller homes; Collies suit families with room for a big dog.

Shared Scottish roots

VCA explains that the Collie originated in Scotland in the 1800s, in rough and smooth versions first called Scotch collies: the smooth dogs drove sheep and the rough dogs stayed out with the flocks. Queen Victoria's enthusiasm made the breed fashionable, and Albert Payson Terhune's stories and then Lassie cemented its family-dog reputation in America. The AKC calls it one of the world's most recognizable breeds.

The Sheltie comes from the Shetland Islands, where sparse land favored small livestock and so small herding dogs. VCA says Shelties almost certainly descend from the same early collie-type dogs as the Collie and Border Collie, and herded sheep, ponies and chickens away from unfenced fields. They were first shown as Shetland collies until Collie fanciers objected, which is how the name changed.

Temperament

VCA describes the Collie as a gentle, devoted companion, playful and very good with children, good with other dogs and pets, quick to learn and eager to please. It does well in dog parks. Its main drawback, per VCA, is overly enthusiastic barking. Collies are usually friendly with visitors once introduced.

Shelties are loyal, biddable and gentle, and VCA calls them excellent companions for children, though they may nip at heels when excited. They tend to be a one-family dog, aloof or even shy with strangers, so early socialization matters, and some are timid. VCA says most bark a lot and are sensitive to correction, so they need gentle training. They rank among the most accomplished breeds in agility and obedience.

Grooming and shedding

The Sheltie is the higher-maintenance coat for its size. VCA says brushing and combing every other day is needed to prevent mats, and shedding is above average. Pay attention to the fluffy hair behind the ears, the mane and the trousers on the back legs, where tangles form first.

A rough Collie's long, thick coat needs a good brushing once or twice a week, while a smooth Collie needs only a brief weekly brush, according to VCA. Collie shedding is average to above average. With either breed, use a pin brush and an undercoat rake, and expect a heavy shed seasonally. Brush down to the skin, not just the top layer, or mats form underneath.

Exercise and space

Neither breed is hyperactive, but both are herding dogs that need daily activity and mental work. VCA calls the Sheltie a calm yet alert housedog that enjoys herding, agility, games and tricks. The Collie, it says, is a well-mannered housedog given adequate exercise, enjoys cold weather but cannot live outside in it, and benefits from games and tricks for mental exercise.

Size makes the real difference at home. A Sheltie fits comfortably in an apartment if you can live with the barking, while a 70-pound Collie needs more room, a bigger car and more food. Both should be walked on a leash, with a well-fitted dog harness if you prefer one, or in a fenced area, since herding instincts can make them chase moving things.

Health and which to choose

Both breeds tend to stay at a good weight, according to VCA, though their coats make it hard to judge: feel under the fur for the ribs. Ask breeders for eye and hip screening of both parents, and ask your vet which health checks matter as your dog ages.

Choose a Sheltie if you want a small, highly trainable, devoted dog that excels at sports and does not mind its barking or reserve with strangers. Choose a Collie if you want a bigger, gentle, people-friendly family dog with a slightly quieter voice and have the space for it.
