Who will win?

Not just fight, but win. I only have 1 pokeball left

The Kingler is a wild Pokemon, the Labrador however is trained, possibly giving it a higher level; IVs and Friendship are probably maxed. It's also been taught moves that stratgicly gives an advantage. Kingler's what typing doesn't give any dis/advantages, however it has many fighting moves at its disposal, which depending on the Lab's typing it could be bad (Normal OR Dark), really bad (Normal/Dark) or ok (Normal/Fighting). But being trained, it'll probably win.
