Shaun Burke used a large dildo to repeatedly whack a woman over the head in a dispute over ownership of a pet dog.
He wore a leather gimp mask during the attack.
He stole the small Lhasa Apsa dog, called Apso, took it to a nearby park and taped it to the trunk of a palm tree by the neck, killing it.
Judge David Searles described the facts of Burke's case as grotesque and said the assault on the woman had severe emotional consequences for her.
Burke, 40, a diesel fitter, pleaded guilty in the Mackay District Court to five charges including burglary involving assault causing bodily harm, and stealing and killing a dog at night.
