You'll have to be a little more specific with your problem if you want useful advice.
...That's not essay-length.
I already killed some dogs, and I have some cats in a pasture, but both my water buffalo died because I remembered about pastures after it was too late. I'm waiting for kittens.
If you haven't already, render the fat and cook the tallow produced. The kittens may not be any good for immediate butchering, as they're rather small and may produce only a skull.
What's the wildlife like? Sending out the military to kill it directly is one option, and channelling out the ground to force creatures into a cluster of cage traps is another.
My main problem is my plump helmet and wild strawberry industries are stalling. Can you brew wild plants? If so, I'm fine.
Oh, and some kobolds got me before I setup a military, meaning they took most of our brewable food.
You can use wheelbarrows as bait items. They're useful in their own right, made from one piece of wood, and are rather valuable. Spiked balls are also valuable and made from one log. Storing valuables behind pastured animals and meeting areas is a good idea, as it gives thieves more pairs of eyes to get past.
You can brew wild plants just fine, at least the ones that are brewable. Sometimes I make the plant stockpile exclude blade weed, hide root, and dimple cups. They can't be brewed or cooked, and since the herbalist will always haul plants to the stockpile they're just a waste of time in a fortress that's in need of gathered plants.
Above-ground plants can be grown all year round. Grow a mix of berries and other, brew-only plants.
