Canes Venatici is a constellation in the Northern Hemisphere. It is visible in May.

A star in Canes Venatici, Y Canum Venaticorum, is one of the brightest and reddest carbon stars in the sky in addition to being one of the coldest visible stars. It was named "La Superba" by Angelo Secchi in the 1800s for its color.


The two dogs in Canes Venatici are sometimes presented as the hunting dogs of Boötes, named Asterion and Chara. They are unrelated to the dogs associated with Orion (Canis Major and Canis Minor).
