I finished this a couple of months ago, in some painting I was doing for the Game of Thrones project, but he was originally purchased to be used with my dark ages villagers - a hound master for the town. I picked up the models quite cheaply from eBay - it's a blister sold by Warlord Games. There was also a third hound but unfortunately the legs snapped and were far too thin to pin back together.
I think he'll be useful in certain scenarios - I can imagine him being used by the local lord to track down a werewolf's lair or to hunt the last survivors of a failed raid.
Comments and suggestions are most welcome - thank you for reading!
