A European Grey Wolf in summer coat at Paradise Wildlife Park, United Kingdom.
So no more comments about the Vlcaks not having fur or being defective, k? I realize that a lot of people, breeders included, want to only see a nice, heavily coated one. Anyway in a summer coat you can see the proper structure much easier.. 
It is written already in the FCI breed standard:
"COAT
MAKE UP OF COAT: Straight, close. Winter and summer coat differ greatly."
I would say even more: wolfdogs which do not shed can be considered as untypical Czechoslovakian Wolfdogs (it is very likely that the dogs have thick coat for the whole year "thanks to" genes inheritated from the German Sheopherd Dogs which are responsible for (untypical) long hair)
but it depends what do you mean by summer coat, I agree with Margo longhaired german shepherd in summer looks like this
ALL wolves shed - here one example of AWD: winter coat:
And summer coat:
And more European Wolves in sumer coat:
And the same animals in winter coat:
(take a loot on the open coat )
I know, but it seems some people really cannot read.....
