[Fluffagrams]

The main difference will be the size but Syrians and Dwarfs are more prone to different health conditions too so Dwarfs are generally more prone to diabetes but Syrians can be afflicted by wet tail or torpor where dwarfs don't.

I don't know if it's just my Syrian but female Syrians seem to smell far more when they're on heat than any of my Dwarfs ever have.
