This is a small mod which adds a few new pets which can be trained to war/hunting status.

Hawk - a good flying predator, though too small to hunt anything large
Cave bat - a big bat which can suck the prey's blood.
Monitor lizard - fast amphibeous creature. Train them to guard your underwater entrances.
Crusifer spider - a tame version of spider, of size of the dwarf.
Blood spider - though it's poison is not that deadly, his bites take a lot of blood from its victims.

This is just a single file so feel free to include it in any mod if you like, it won't break the compatibility.
