|Artwork of Hot Dog from Mega Man 2|
Hot Dog (or Friender depending on localization) is a blue dog robot that was originally meant to protect forests. They have a fire extinguisher on their tail but Dr. Wily modified them to be able to breathe fire. They originate from Mega Man 2 and appear in Wood Man's stage. It also appears in Wily 2 of Wily tower in Mega Man: The Wily Wars.
When Hot Dog is spawned, it will teleport in like Tama giving you a moment to freeze it with the Flash Stopper if you don't feel like fighting it. Else it will shoot fireballs until it dies. Hot dog will not turn around if you go behind it.
Hot dog is weak against Leaf Shield, a weapon that can kill him in just one hit, although it could also be said (though not officially) that it is weak against Shine, since he returns the necessary amount of fireballs to kill him.
Hot Dog also appears in Mega Man: The Wily Wars and Mega Man II.
Hot Dog's fireballs do not have the same hitbox as it shows, meaning you can be a little inside the fireball without taking damage.
