I wasn't going to say any thing, but the main problem is someone is already making zombie wolfs in plastic.
Ugh. Can't say I like GWs interpretation of zombie dogs. Looks to me like there is room on the market for someone else to do them.
Reaper also does a Zombie Dog and Handler in pewter.
At $6 a pop it's pricey to buy just for the dog. Hopefully they will make more as the detail on it is awsome.
Reaper's is a bit more likable - would rather have that in plastic than the GW one.
It may be more reasonable than $6. Reaper has what they call their "Boneyard", which is like GW's Bitz service. It's not currently online, but you can call them up and order just about anything that is a seperate piece. Doesn't look like that model is two seperate pieces, but if someone were truly interested in the dog's seperately, I'd definitely call them and ask. Who knows, enough people call, it might inspire them to do a seperate dog casting. They've been known to do variant miniatures of previous releases.
