Swelterrier

Swelterrier appeared in 2013 video game called Yo-Kai Watch. Swelterrier (Japanese: あつガルル Atsugaruru) is a Rank S, Fire-attribute Rare Yo-kai of the Charming tribe.

As of Yo-kai Watch 2, Swelterrier is one of the Yo-kai required to unlock Komashura.

Swelterrier has a similar appearance to Chilhuahua, except that he is red colored instead of blue. The inside of his ears and the bottom of his cape are yellow, but most of his cape is pale pink-ish.

He has the qualities of a well-mannered leader and respects his entourage with ease. However, when Blizzaria is around, he becomes very meek.

Wherever he is and where he goes, Swelterrier can make the place extremely hot.

In most of his anime appearances, he is seen as the leader of the "Hot Clan" conformed by Sproink, Blazion and Swelton. They are seen together when doing parties. In EP091, they form the 'Atti Soul Brothers' musical group to compete in the White and Red team battle.

Swelterrier and Blizzaria have a very turbulent relationship. Despite Blizzaria trying to hang around with him under believing that Cold and Hot groups are more equal than different, she does not realize she is causing more harm than good -albeit unwillingly- with her ice powers. In turn, Swelterrier seems to panic when Blizzaria encounters him.
