About

In the same way that other races have tamed animals to serve them, kobolds keep a variety of large reptiles. While not intelligent enough to be trained in the same way as a horse or worg, these creatures know who feeds them and will usually do their bidding, though it is not unknown for primitive instincts to take over in stressful situations. Unless secure in a seat on their back, kobolds will usually simply turn them loose on a foe before putting a good deal of ground, and preferably some sort of barrier between themselves and the beasts.

Scutico, or scale-rats, fill a similar role in kobold society as dogs do above ground; some kobolds with a rare sentimental streak may keep them as companions, but they are mostly used in large hunting packs to run down and harry subterranean game.

Kept by most colonies as a waste disposal and perimeter defense, svaraskalos lizard-hounds are usually kept in their own chamber due to their unpredictable nature. They will tolerate being ridden only by kobolds who are very familiar to them and view others as prey, though they prefer their food warm-blooded.

The seismosuchus is a huge burrowing reptile occasionally used by powerful kobold colonies to aid in the expansion of their tunnels either by leaving bait, goading the beast, or simply following in its wake and hoping for the best.
