Hot Dog possesses a fierce loyalty to his friends, and true to his nature, he likes to bury things, especially imps.
Hot Dog was born in the belly of the Popcorn Volcano. While on a nearby mission, a team of Skylanders had come across the stray fire pup when the volcano erupted and Hot Dog came rocketing straight into their camp, accidentally setting Gill Grunt's tent on fire. Using his nose of danger, he helped the Skylanders complete their mission - even pouncing on a lava golem like a blazing comet when it threatened his new friends. After displaying such loyalty and bravery, Hot Dog was brought back to Eon's Citadel where he became a Skylander - and then he proceeded to bury Eon's staff.
