Hot Dog...?

 is a consumable item sold at Sans's stand in Hotland only if Papyrus is alive. The stand is located immediately to the left of Elevator R2. Consuming the item makes a barking sound (Unless in Serious Mode).

Additional Uses

 * Giving a Hot Dog to the rightmost door in MTT Resort rewards a Hush Puppy.

Trivia

 * Its "meat" is actually made of a Typha plant (or "water sausage").Head dogs.png
 * The second time a Hot Dog is bought, Sans will give a Hot Cat instead.
 * The Hot Cat heals for 1 more HP than a Hot Dog, makes a meowing noise when eaten (Unless in Serious Mode), and cannot be exchanged for a Hush Puppy. It also sells for 1G more than Hot Dogs.
 * The third time a Hot Dog is bought, Sans will note that "[the protagonist] really [likes] hot animals". He says he's not judging though, as he'd be out of a job without folks like that.
 * If the inventory is full, Sans will place a Hot Dog on the protagonist's head when attempting to buy one. He does not charge for this.
 * Sans will do this up to 30 times. Instead of placing a 31st hot dog on the protagonist's head, he notes that 30 is an excessive number, and that he can't reach any higher.
 * If the protagonist moves with a stack of hot dogs on their head, the hot dogs will fall off. The hot dogs disappear when the room is left.
