Balancing Casting & Strong Lining
once you start casting, you will often see dogs that will not take as strong of a line or "pop". We cannot have this, which is why we need to keep balance in our retrieves, lining the dog out and not stopping them on retrieves just as often as we do.
This will ensure they continue to run strong when we send them, and avoid a "popping" issue where they run so far and stop on their own looking for help when they shouldn't.
