@ blade: as i said arcanine is better all-around. it won't force switches, which are made bad by stealth rock. and arcanine can defend from sweepers and get past walls.
@ZLS: i would have thunderbolt, for double or multi battles.
also, how do you challenge frontier brains? idk how...
All around isn't what people use competitively, and if
you're using Stealth Rock, you'll want to force switches, though Stealth Rock won't help if your opponent has a Rapid Spinner.

And Defend from Sweepers? Water+type of the weaker stat, physical or Special, on a dedicated sweeper+Life Orb+Atk boosting nature+Other factors=Arcanine going down, no matter how balanced it is in it's stats.
And you challenge them by participating in a certain Frontier Building, building up a streak until the brain appears.
