I don't think so. Take a look at the Groncicle description. The description "yells" out "this dragon is cold blooded!" (exclaimation mark) Did they have to make it obvious? That tells me that other dragons are warm blooded. Idk about the Snow Wraith, it might be warm blooded too, but also a big possibility of cold blooded. But we can't confirm it.
