It seems to me that the Iron Shadow Hobgoblin is an excuse to let the monks in a party announce to the vanquished bad guys that "my Kung-fu is stronger than yours!".
Yes! They have a doglike nose in this edition. Prior to 3rd edition, they were actually more like a rat than a dog.Aren't kobolds a bit more doggish in this version, art-wise? Its interesting to see them mix a bit between the dominant 3e and 4e lizard types, and the older 1e and 2e dog ones.
