Brushing Kangal Dog Lokum / shedding 5-6-17

Kangal Dogs shed off their thick winter coats in the spring. Interesting note, Lokum is shedding before Sarah. Sarah really hasn't even started yet, Lokum began shedding a couple weeks ago. We got him from southern IL and I wonder if that has something to do with it, or is there some other reason? It seems to me that his internal clock is still set to southern time. Night times are still pretty chilly here currently so I have a hunch that's why Sarah has not begun to shed yet.
