Caninicide

The last canine to be hurried to an untimely end was "Prince," the especial pet of the Bones family, and Prince's death proved to be the last straw. As he could not be connected with the chicken-killing, the taking-off of poor Prince was deemed to be unjustifiable caninicide, and Gager will have to take his medicine today for shooting the poor beast.

So he got a pistol and shot the dog. The court held he had no right to do it. A clear case of caninicide!

Bong Joon-ho's Barking Dogs Never Bite (2000) isn't exactly horror - unless you're a dog. A brilliant black comedy about a henpecked husband driven to caninicide, it features several eye-popping scenes of animal cruelty that belie the opening credit claiming no living creatures were injured during the making of the film.
