Peter Pig's Scenery range, & are only 6-7mm tall, but nevertheless very nicely detailed. There are 3 unique sculpts in each 8-figure pack - I've painted them up as a golden retriever (or yellow labrador), border collie, labrador retriever, terrier cross-breed, & a German shepherd. They are all mounted on 1p coins, which are flocked using Gale Force Nine dead/winter grass & dirt. I really enjoyed painting these, & will probably pick up some farm animals to enhance my rural setting.
In Ambush Z rules terms some of these could be used as police or Military Working Dogs to sniff-out the zombies/Infected, but I'd like to add some house rules for encountering stray dogs as areas are searched - dogs which may be friendly, or alert the Infected with their barking... Also, I think a scenario with guard dogs acting as alarms for survivors in a safe house could make for a good game.
I did consider painting one to represent my own dog (a cheeky Alaskan malamute), but it was too sad to think of her in an apocalyptic setting! In the future I will paint another labrador & a German shepherd, but on desert bases, as MWDs for my Force on Force collection. If I ever branch-out into Crufts miniature gaming, then I have a decent starting point! :-D
