Mark Hook, 38, admitted to RAPING his friend's Labrador numerous times as well as other deviant sex animal cruelty crimes against the animal.
Hook recorded video of him abusing and RAPING the dog and shared the videos with other sick perverts via the apps Skype, Kick and Whatsapp.
He was sentenced to three years and two months yesterday, the Bristol Post reports.
Bristol Crown Court heard how Hook CLAIMED he had descended into drug-fueled spiral which saw him downloading the most extreme kinds of child pornography and animal pornography before acting out his sick fantasies with the poor dog on a farm in Somerset.
Hook, from Hartcliffe, lived at his parent’s house following the collapses of a long term relationship.
He rarely socialized, instead preferring to spend his time alone in his room where he snorted the drug Mephedrone, drank and shared vile images with an online community of pedophiles.
He was arrested after police found messages from him on the computer of another man.
Hook had been sharing perverted fantasies with the man about child abuse and bestiality / animal cruelty – using the nickname DirtyBristolBoi.
Hook’s iPhone, laptop and hard drive were seized by police in April 2016 and officers found dozens of child sex images, some involving babies.
The judge said Hook had been viewing "the worst kinds of sexual acts imaginable against a human being".
Prosecutor Richard Posner said Hook had shared the sado-masochistic porn with others.
Hook also had 797 "extreme pornographic images" depicting men and women having oral and anal sex with dogs, horses and cows.
The court heard Hook began acting on his perverted urges in late 2014. He had a friend film him being penetrated by the Labrador on a farm in Somerset.
Police found 20 videos of Hook
Hook was charged with ten counts in all, relating to creating and distributing child pornography and extreme pornography as well as
Judge Horton said Hook was a "part of a network that processed, shared and facilitated the making of these images".
Robert Duval, defending, said Hook was of previous good character and that this would "come as a cataclysmic shock" to people who knew him.
He CLAIMED that following his arrest Hook had made a "concerted effort" to kick his drug habit and seek counselling for his problems.
Passing sentence Judge Horton said: "Abuse of drugs proved a gateway for him which meant there was nothing even vaguely rational about what he watched and what he did with the images and with his own body.
"He spent time with the worst people imaginable and got into a pattern of life into which he completely disappeared."
Judge Horton sentenced hook to three years and two months for his crimes, telling him: "You are part of an ever-growing plague of men in this society who present as men of honesty, integrity and family values.
"But behind closed doors in reality you conceal very dark secrets. You sit in private rooms with computers and seek out the most appalling sexual degradation and abuse of young children and babies.”
An NSPCC spokesperson for South West England said: “The children in these pictures are the victims of child abuse and the horrific experiences they endured for the images to be created should not be underestimated.
"The proliferation of abuse images online is a growing problem, fuelled by offenders like Hook.
"More needs to be done by internet providers, governments and law enforcement to cut this material off at the source, but even then there is no guarantee that the existing abuse images will ever disappear from the web."
If any adult is worried that a child may be being abused, they should call the NSPCC Helpline on 0808 800 5000. Help for children and young people is available through Childline on 0800 1111.
