So, I decided to give the newest update a try a few weeks back (after a long break from DF). This is my second fort since then. Everything was going well, until four kobold ambushes (two bowbold squads, one axebold squad, and one swordbold squad) right after a goblin siege. Having let my guard down from dispatching the goblins, the gates were wide open, haulers were collecting bodies, and the military were either drinking, or getting upgrades to their armor (iron -> steel).
'Ambush! Skulking vermin!' four times. (Not simultaneously, of course)
The only thing that were able to keep the kobolds away before the first military dwarf showed up were the hunting dogs that were assigned to many of the haulers and passerby (standard issue). No one was hurt, but lots of hunting dogs were killed, as well as the entrance hallway being filled with bodies and blood. (a goblin siege barely made it there, but a bunch of kobolds did... I am disappoint)
So, that's when I noticed there were no puppies or stray dogs to train. I recall how in the first year or so, the female dogs were having puppies like crazy. Now... nothing. Haven't seen a single stray dog or puppy around. Thinking back on it, not a single '____ has given birth to puppies' announcement has been given for awhile. All dogs are either assigned hunting dogs, or pet dogs. Is this something new implemented? Like, birth control or something?
Apologies for this being a little wordy. Just read the bolded parts.
