Oh, yeah. Other things I should mention
* Visiting surface animals have dropped to zero (I get the occasional kobold thief, magma crabs and fire imps in the volcano and nothing else).
* I have been using dfhack, but only autodump and interface enhancements. I'll disable it and see if the problem continues.

Oh ho! I've got puppies again - which means it was probably a DFHACK issue. This can be closed (unless it repeats in a non dfhack game).

EDIT: Although the other thing I did was buy a dog in a cage - I didn't let it out though. Can caged dogs get dogs outside of cages pregnant?

Wasn't there a total limit for animals on the map? Maybe that has been reached?

@clanl
I'm not sure if maps have a total limit for animals, but that doesn't explain why disabling dfhack changed things. Also, there were hardly any animals visible on the map except for the dogs. (I don't know if animals build up in caverns before you reach them).

I've noticed some non-grazer animals do not breed at whatever reason. In my current fort I embarked with 2 pigs (both genders) and two sheep (both genders.) After few years, I had 10 sheep and 2 pigs. Now at year 9 of the fort, I have captured and tamed rhinos, giraffes and rutherers, all who breed like no tomorrow, but piggies apparently are not feeling like it..or maybe they now are too old for good ol' porking. The baby/pregnancy cap is not reached either, since all other animals keep popping up babies. Heck, I just butchered 5 puppies that were born to the two pet dogs ages after I had gelded the male one. (Because why bother with war dogs, when you can have war rhinos and.. war giraffes! I'm still giggling on the image of that.)

@ptb_ptb:

Yes, animals migrate in and out of caverns before you discover them. You can use "reveal" on an old save to see if any of your caverns are packed full of wildlife.

@Muumeh:

You're probably encountering 0007651, where animals that are "unwilling to marry" are also unable to breed.

In the posted save you have nearly 50 dogs (and another dozen dead dogs). There is a per-species population cap around 50 which prevents further breeding, so I'd say this behavior is working as intended. As your dog population falls below 50 you will receive another round of births pushing you well past 50 and halting breeding until your dog population falls below 50 again.

From the notes here, it seems that this can be resolved as no change required. If you disagree, please reopen the issue or PM one of the managers on the forums.
