The killing of a dog, chiefly where the death is not in the
best interests of a dog. A veterinary surgeon who gave a lethal
injection to kill a dog in pain would not be
committing cananicide.
You put your
clean linen on the
washing line outside to dry, only to find your dog later has
pulled it down, and it is filthy and needs to be washed. You are furious with the dog, kill it and you have committed cananicide.
Thoughts of cananicide are common amongst owners of "canine menaces" and those who loathe dogs.
