Relaxation protocol for a herding breed?

I recently became a proud owner of a 9 month old Kelpie pup and it's my first time raising a herding breed.

I have a 4 year old labrador in addition to that who I raised from 8 weeks, and had a lot of success managing her energy with crate naps, relaxation protocol and food toys to the extent that I only have to exercise her a moderate amount without her getting destructive. As an adult she sleeps 20 hours a day and is rather easy to take care of for being on the high end of energetic for a lab.

I know the energy needs of herding breeds are far higher than labs, so I was wondering whether this approach would still work and how much exercise I would need to provide her with in addition to that.

Thank you in advance.
