Caninus was an American deathgrind band formed as a side project by Most Precious Blood guitarist Justin Brannan, Rachel Rosen, drummer Colin Thundercurry and two female pitbull terriers, Budgie and Basil. They were signed to War Torn Records and had three releases, including a split with Hatebeak and a 7" split with death metal band Cattle Decapitation. In 2008, Richard Christy played the drums on an unknown number of songs for Caninus.
On January 5, 2011, Basil, one of Caninus's pitbulls, died. Basil had been diagnosed with a brain tumor and was euthanized. The band has ended because of the dog's death. Vocalist Budgie also died in early 2016.
