A Storm of Swords
Iggo is part of a four-man squad of Brave Companions searching for the escaped Nan (actually Arya Stark), Gendry, and Hot Pie. Iggo's group is set upon by a pack of wolves. The others die and Iggo kills two of the wolves, but has his arm ripped off and is slain by their direwolf leader, Nymeria who may be protecting Arya. Arya herself experiences the scene through a wolf dream.
