Sex offender 58 'held pregnant woman hostage and forced her to have sex with his brown and white pet dog'

A pedophile registered sex offender allegedly forced a pregnant woman to have sex with a dog at gunpoint and filmed in on his phone.

Dennis Allen Carter, 58, was charged with bestiality and three counts of aggravated sexual assault after he was arrested in Houston last week.

He was out on parole for another aggravated sexual assault in 1997, and was convicted of sexually abusing a child in 1981.

Carter put a gun to the woman's head and demanded she perform oral sex on both him and his brown and white pet dog or he would kill her, police alleged.

He 'kept telling her to "quit screaming" and slapped her multiple times' during the ordeal on August 7 last year, according to court documents.

The woman told detectives Carter picked her up from a petrol station on Crosstimbers and Hirsch and took her to his house in Kittridge.

The alleged abuse began that day and was filmed and photographed on Carter's phone, which was later recovered by police.

Carter fell asleep afterwards, but the woman was locked in the house and unable to leave until she was taken to another petrol station in the morning.

Police received a tip off from the woman's friend and she was able to escape long enough for officers to rescue her.

After months of investigation, police charged him and filed a motion to revoke his parole to keep him behind bars after he was given a $350,000 bond

Darter was hauled in for questioning the next day and showed police the photos and three videos on his phone, which he claimed were consensual.

After months of investigation, police charged him and filed a motion to revoke his parole to keep him behind bars after he was given a $350,000 bond.

'The facts in this case frankly sound like something out of a horror show,' the prosecutor told the court, according to ABC.

Carter was required to register as a sex offender for life after his previous sex crimes.
