The hydra is traditionally classified, historically speaking, as a dragon. Pretty much any Reptile of Unusual Size was/is. For reference, see: Wurm.

For real-world reference, see the Lambton Worm, one of the most well-known real-world Wurm myths/legends. Clearly, it starts out as more of a serpent, yet it is historically considered a dragon due to its massive size(able to wrap around a local hill seven times, according to the stories).
