There are many key differences between scotch collies and rough collies. The scotch collie predates the rough collie, and was the original inspiration for the breed. Given that the scotch collie was never recognized by the AKC, the physical appearance of the scotch collie varies far more than the physical appearance of the rough collie. Finally, the scotch collie lives a slightly longer lifespan than the average rough collie.
Let’s discuss all of these differences in more detail now.

One of the most interesting things when comparing the scotch collie and the rough collie is the fact that the rough collie has a set size and weight, while the scotch collie comes in a variety of heights and weights. This is because the scotch collie is not technically a purebred breed of dog, and its appearance is not regulated as much as the rough collie.
For example, the average rough collie is 20-24 inches tall according to its breed standard, while the scotch collie is anywhere from 17-26 inches tall. The scotch collie may weigh either more or less than the rough collie as well, due to unregulated breeding sizes. The average rough collie is 40-65 pounds, while the scotch collie is 35-70 pounds.

You can tell that the scotch collie and the rough collie are related, but there are some differences in their physical appearances given the fact that scotch collies are unregulated dogs, and rough collies have a set purebred standard that they must meet. The rough collie has a long and straight fur coat, while the scotch collie typically has a less impressive coat overall. However, both of these dogs are found in the same colors and patterns.
One of the main ways you can tell the difference between a rough collie and a scotch collie is that the rough collie has an impressive rough fur collar around its neck, while the scotch collie rarely has this feature. It feels like the rough collie is the more elegant version of the scotch collie, but they are both beautiful and capable dogs.

One of the key differences between the scotch collie and the rough collie lies in their ancestry and breeding. Both of these dogs were bred for herding sheep and other farm animals, though the scotch collie is the reason that the rough collie exists. Let’s discuss the history of both of these dogs in more detail now.
Originally bred in Scotland, the scotch collie was used during the 1700s, while the rough collie was first bred in Europe a bit later. The rough collie was designed to be a more beautiful and more regulated version of the scotch collie, while the scotch collie remained unregulated and free to look however they wanted. In fact, the rough collie almost made the scotch collie breed obsolete, though there are recent efforts to revive this beloved dog.

A final difference between the scotch collie and the rough collie is their lifespans. The Scott collie lives a slightly longer life than the rough collie overall. Though it always depends on the health of the individual breed. Both of these dogs have a decently long life, especially when you consider their size.
For example, the scotch collie lives an average of 13 to 15 years, while the rough collie lives anywhere from 12 to 14 years. Given the health and dedication of the majority of herding dogs, you can expect a long and happy life from either of these two breeds.
