...This was a good solid 5-10 minutes of brushing and about all the longer I could hold him still. Looks like I killed and skinned him instead of just brushing him and there is plenty more left. Its crazy how much fur is I that sub-coat!
You could hold him down for 5-10 minutes ?
I could barely hold mine for 5 max. Mine (Silver Trace) looked very much like yours... just a darker grey/white mix with a stunning wolf head - an ex-show dog. Shed just as bad. Do what I did... collect the hair, make a pillow.
