This is a club created by two mid-level youkai. Depending on the situation, the name may change to something like "The Club for Selling Gratitude to Natsume-sama", and it is a club like a club. They have a variety of activities, such as going to drinking parties and helping out Natsume.

This youkai has appeared since the beginning of the anime and has appeared relatively frequently throughout the anime. He is a one-eyed youkai and does not have an official name. Takashi calls him intermediate. He is quite a cocky guy, offering "alcohol" to Takashi, who is underage. Although a similar monster appears in the story, it is a different monster.

Like the one-eyed monster, this monster has appeared since the beginning of the anime, and looks like a cow. Like the one-eyed monster, it does not have an official name. It is a monster that does not know many words, and often repeats the words of the one-eyed monster.
Hinoe

She is a female curse user who was summoned by Misano when Takashi was cursed by the Five Days of the Moon. She wears Japanese clothing and uses a pipe. She loves Reiko, and when Misano called Hinoe, she was told that "Natsume is calling her" and she thought it was Reiko. In fact, she hates men, but likes Takashi because he resembles Reiko.
Misuzu

A demon with a horse's right hand and a human's left hand, a large body comparable to a human's body and the spots on a horse's face. A demon with a name in the Book of Friends. When the Book of Friends was given to Takashi, he tested him to see if he was worthy of being entrusted with the names, but decided that he was not worthy. He did not ask for the names back, and agreed to cooperate.
Chobi

He is a demon with a large head and a small moustache. He considers himself a noble demon. She seems to be a noble demon, as she called the Great Demon Nyanko Sensei's barrier "tinke" and broke it. She ends her sentences with "~desu masu" (~desu de arimasu), which makes it seem like she is speaking politely, but she can also be quite sarcastic.
Benio

She wears the same kimono as Hinoe and is a female demon who has no qualms about eating people. She has a butterfly on her right eye. She is an old friend of Nyanko-sensei and calls him "Madarama." She also pities Nyanko-sensei in his beckoning cat form, calling him "tiny." She also shows a cooperative attitude towards Takashi after he helps out Riou, the master of Koho. She is also one of the few youkai that Takashi calls by a title of respect.
Kappa

A low-ranking kappa-shaped youkai who calls Takashi "Boss Natsume." He was rescued by the roadside when the plate on his head was dried out and dried up. There are several scenes in the story where he is rescued from being dried out.
Summary

I've put together a summary of the Dog Club. What did you think? From big-name to low-ranking youkai, various youkai participate in the Dog Club. I think that shows how attractive Takashi is.
