忠吉さん
[[Azumanga Daioh]] character. For the [[Ukagaka]] character, see [[Tadakichi (ukagaka)]].

[[Mihama Chiyo]]'s dog. A Great Pyrenees who's enormous compared to his master, and not even that big for the breed (these things can reach the size of a grown man). He's not quite aware of this and has been known to knock Chiyo-chan over in his enthusiasm. He has big dot eyes, a permanent smile, and all the usual dog habits. [[Sakaki (azumanga daioh)|]] is almost as fond of him as Chiyo-chan is.
