First off, my comments about the hair are completely, 100%, thoroughly nitpicks of the cover artwork. Other than that, I like the artwork and cover design, and this book already has a reserved spot on my Traveller book shelf.

We evolved from hairy apes, why do we have hair on the top of our heads?
At 300,000 years ago, we had already diverged away from apes enough that the hair on our heads was a distinct feature. Hair like that probably wasn't a distinct feature on the canine stock that Vargr were derived from, I'll bet. Even today no breed of dog I'm aware of has a head of hair like that, unless it's a long hair breed groomed that way.
But that's not my key gripe about it. The "hair" thing makes me think of "furries" artwork, where any and every animal you can think of is anthromorphized, typically by making them stand upright and adding hair. So I take the hair as saying "this will make them look more human." And despite being uplifted Terran animals, they are aliens, NOT humanized dogs.
The only reason I don't have the same complaint about Aslan is that their hair resembles the mane of a lion, and explains why Terrans dubbed them Aslan upon meeting them.
It's a minor point, though - until/unless someone actual sculpts an official line of miniatures for the Vargr looking like that, I'm not going to get upset about it - I'm just putting my opinion out there, since it was my first reaction to the cover/product.
