What kind of dog and pony show? The kind without dogs. These two packhorses are from 15mm.co.uk. They come one each in their adventurer's packs. As you can tell, I've got two adventurer's packs to paint. The thief is from that same pack.
Here is a comparison shot of the same figure with two 10mm pack horses from Pendraken.
And here is a group shot of all of them together. My plan is to use all four to varying extents. The 10mm figures look like ponies or maybe even donkeys or mules. The larger ones are obviously full grown horses. With this lot I've got a nice little caravan perfect for those longer expeditions to the lost city of Cynidicea.
