oh YES..we call it the Mohawk here too..although I have noticed Pippin's fur on the back is slightly thicker maybe, because it looks darker than other areas, almost all the time..
All of ours have done this at one time or another during times of stress.
yep, all the time. both boys do it. especially when they "think" there is hunting action coming up… which is all the time. and when inconsiderate people let their dogs run around off leash as we are out walking and said loose dog comes up to them and gets in their face. happens almost daily. very very annoying those owners of loose dogs... hum.
And they both get it when anxious,nervous,meeting someone new,someone knocks on the door rtc…
Yep, it is what Watson does when first meeting a new dog. Once he has established that they are okay his hair settles back down along with the rest of him 
Kipawa does it too - usually when meeting new dogs or encountering something odd, like the snake we came across last week.
Hopper does this too! mohawk!
Anubis does it a lot too…a new person comes over...a strange dog comes near him...some strange animal...when hes in trouble...everything makes him do it. I think its cute! It feels all fuzzy too lol. Ill try to comfort him and pet his back and I tell him to Put His Hair Down lol. And he does too
YES, Ayo does this all the time!, At first I used to freak out thinking he was about to get aggressive , but I have noticed that he does this almost every time hie melts another dog and hardly ever odes he get aggressive. it's just something he does , I always figure since he doesn't bark!!!
Yep Tenji does it also, I call it his "Mr. T" look though.
