Yes, I've noticed that too and I understand that sibes are not big, and supposed to medium-sized working dogs, but most show dogs don't seem to convey "work" at all.
And I'm pretty sure mine isn't show lines but I'm positive. This is him on his 1st birthday and he just recently started to blow his coat.
Yes I've seen some show quality huskies here in California, they look very "pugdy". I wouldn't fat but the seem to be short on leg and their fur fluffs out. They hardly look like lean, hard working dogs. Which is why I'm working hard to keep Maxx nice and lean.
