[Albertosaurus Rex]

The Malazan books feature a pack of dog gods known as the Hounds of Shadow. They're described as being as big as mules, so I figure the dogs on House of Chains are something else, although perhaps related in some way?

I don't particularly like dogs myself. In fact, I always feel uneasy around even the smallest of dogs. This is probably why the passages involving the Hounds of Shadow worked very well for me - when Erikson tries to make them threatening, my mind is already halfway there.
