Dog leather journal?
How many did you butcher, butcher?
Speaking of which, what's the kennel for?
As for that archery tower...Won't the invaders dig through it, hm? The bolts will not kill them by the time they reach the walls, assuming they don't go diagonally straight to below from map edge.
Though it is still useful against giant wildlife and preparation for accidents. Mm, giant buzzards.
Though Mistem will probably be the happiest with four dozen rose gold bars produced in the fortress. She gets to personally work on them, on top of being a mother!
I actually built the kennels out of habit. When I started playing DF, you had to war train at them, and I always seem to build one before I remember I can war train with just an animal training zone. As it exists now, kennels aren't THAT useful, though I might just train up a trapper for the lolwut factor.
(a good trapper can catch faster than a fleet of cats can).
I've always wanted to legitimately train up a legendary animal dissector/fish cleaner. The former is hard, the later is borderline impossible (I've never seen a moghopper at all).
As for the archery tower, digInvaders is *very* slow in disassembling things, I think its 1/20th normal Dwarven speed. My plan is to build chains around the tower base, then attach the war dogs there. I may rig the dogs with cage traps or weapon traps. A dedicated attack MIGHT get through, but it will be a long time before the AI really ramps up the sieges. The problem I have to worry about is bolts going through armors. Gobllins and humans can bring iron armor, and 43.03 brings back full armor for enemies.
Invaders should path right to the dogs, and then get bolted to death. I kinda want to go with cage traps as it would allow me to catch megabeasts if there are any nearby, or anything that decides my dogs are tasty.
EDIT: NRDL, your offspring got the nickname Kahlish as it was next on the list. I still have two deferred dorfings left.
