Arcanine? Not bulky enough to resist some of the things Char Y can dish out, and additionally lacks things like Stealth Rock.

The only Pokemon that would maybe even have a shot of doing what Heatran once did is Ninetails, and even then it lacks the resistances and bulk that Heatran had.
Try to help me theorycraft, anon, it's not hard.
