Are sheepdogs naturally workers, naturally protective of livestock, or a bit of both? I've seen them gently herd baby chicks with some tiny nose boops, and was always curious if they were taught to be careful with livestock or if it was just instinct.

I noticed my grandmother, as well as other family members, all started sleeping less and less as their Alzheimer’s worsened. (They would each wake up after a short period, and only sleep 3-5 hrs a day.) I’m curious if sleep disruption is a byproduct of Alzheimer’s or vice versa?
