There had been a promise to get pet war dogs to travel with squads that you send on raids, rather than having them stay home waiting for their masters. So that's now properly completed. If your vision of dwarves is less about crafting in the mountains, and more about a lone dwarf descending from the hills to attack a village with a pack of a dozen hounds, your vision is now a reality. That's how I tested it, anyway. Five of the dogs were struck down, but the humans will now think twice about whatever it was they were thinking about, that's for sure.
So based on Toady's latest post on the front page (see above), I may be using a new strategy next version:
Embark with a couple flux stones, some coal, ores, and approximately 50 doggos (2-3 males in that whole lot). They will all be immediately trained for War, then thrown in a cage by summer. All puppies will be put in cages until they mature. Other war animals (tamed or traded for) get the same treatment, unless Grazers.
I tend to play (mostly failed/failing) small pop generational forts these days, so I will be allowing the first migrant wave (two at most) into the fort (or surface fort) before declaring all others as Meatshields.
Meatshields will be sent off to war with as many war doggoes as possible. The first warroes to go will be males with bad stats, followed by females with bad stats. The best 10 or so female doggoes will be kept for breeding (the actual Ten will be revised every year, when puppies start growing up and become trained to become warroes themselves).
Meatshields will be sent out 1-4 at a time with approximately 30 warroes at a minimum, with the rest of the Meatshields and expendable warroes hanging out in the entryway/maze, training, until weapon traps are fixed.
