Coat length is the only real difference. In most countries the Smooth and Rough count as a single breed shown in two coat types. The Rough carries the long, famous mane associated with Lassie, while the Smooth wears a short and dense jacket. Temperament, intelligence and herding background stay identical across both. Historically, the Smooth served as the working variety used by drovers. Adults weigh 50 to 75 pounds.
Start with the Smooth Collie's own numbers: large size, 50 to 75 lb, 12 to 14 years, and 60 to 120 minutes of daily exercise. Any comparison has to start from a fixed record like this one. Herding breeds notice everything, including things you would rather they had not, per the overview. It rates apartments as not ideal because exercise and brain push outward. Owners describe a dog of unusual sensitivity and devotion: the Collie's whole heart and genius in the practical coat, the shepherd's original choice.
Price and availability differ between the breeds and swing with fashion; the keeping costs, compared honestly on this site, are the figures that follow you for a decade.
The energy rating of 5 out of 5 explains most Smooth Collie behaviour questions: a dog built for work, given 60 to 120 minutes to spend it in. At 3 out of 5, grooming the Smooth Collie is a real but manageable commitment, several short sessions a week for the short harsh flat double coat.
The record in one place: 22 to 26 inches at the shoulder, 50 to 75 lb, a lifespan of 12 to 14 years and 60 to 120 minutes of daily exercise. Most questions about this breed become easier once those four numbers are in view.
Size context from the growth table: 4 months at about 14 to 21 lb, 9 months at about 34 to 51 lb, 24 months at about 50 to 75 lb mark the Smooth Collie's first year, against an adult standard of 50 to 75 lb. The Herding group is where the record files the Smooth Collie; its home ground is Scotland.
Put against the daily exercise bill of 60 to 120 minutes, the picture stays consistent. The Smooth Collie is a fair deal for the household it suits and a poor one for any other, and the record makes the distinction plainly. For the numbers in one place, the Smooth Collie profile collects the size, cost, exercise and health record behind this page.
Children, other pets and housing each vote in the decision. The breed that wins on your household's actual constraints beats the breed that wins in the abstract.
Give the casting vote to whoever will deliver the daily routine, because they live with the 60 to 120 minutes and the grooming sessions. A breed everyone tolerates beats a breed one person adores and another quietly resents. The side by side comparison tool on this site lines the two records up properly, figure by figure.
Insurers price the records, not the looks: the Smooth Collie insures at $42 to $77 a month. A rival with a heavier health record or a restricted breed listing will cost more before a single claim exists. Fashion is the worst reason to pick between breeds: needs outlast trends by about a decade.
Neither breed in any comparison can promise an allergen free dog. Lower shedding, 3/5 for the Smooth Collie, usually means less hair and dander in circulation, and adult dogs of both breeds should be met in person, in homes, before deciding.
Two breeds, one decision: the honest differences that matter day to day.
Is the Smooth Collie a family dog? The verdict, the temperament behind it and the rules that keep it true.
The type behind the breed is very old, even if formal recognition came much later.
