The Small Hydra is born from the head of a Lesser Hydra that has been severed. When the head is separated, the neck of a hydra grows two more, but the more-or-less helpless severed head does more than fall to the ground. It attempts to escape by growing legs, fins, a snakelike body or whatever is needed to get away.
The Small Hydra grows from a severed Lesser Hydra head after 1-2 days. The body and head together is about the size of a small or medium dog. These hydrae are about as smart as a dog as well (but do not get the idea they can be trained outside of a charm spell). They are hostile to all humanoids.
