It is reported that David Buchanan accidentally sent the clip of him and their 10-month-old puppy to his horrified partner.
He appeared at Swindon Magistrates’ Court and pleaded guilty to the incident, which took place early last month.
The prosecutor claimed that David had been watching porn and decided to find out what it would be like to have sex with a dog.
Keith Ballinger told the court: “[The girlfriend] was at work on this day and received on he mobile phone a 29 second video clip from a tablet computer.
“That video showed him having sex with their 10-month-old Rhodesian Ridgeback. When arrested he said he knew he had done wrong and it was stupid.”
Ellen McAnaw, defending, said: “He spends most of his time at home drawing or playing Xbox, and he doesn’t seem to have any friends outside the previous relationship.”
David received a 12-week-suspended sentence for two years, a fine and was ordered to take 50 days of rehabilitation. He was also made to sign the sex offender's register.
