Regarding male weight, up to what point can a Rough Collie often exceed the Scotch Collie standard?
Answer
Can often exceed 75 pounds, sometimes reaching 85 pounds or more
The distinction in weight between the two types becomes quite apparent when observing larger specimens of the Rough Collie. A robust male Rough Collie can frequently surpass the 75-pound upper limit common for the Scotch Collie, sometimes reaching weights of 85 pounds or greater. This additional weight and mass reflect breeding selections that favored a more imposing appearance, contrasting with the Scotch Collie's more moderate and functional build.
