A woman's acts of bestiality with her dog were repulsive and "completely against the order of nature", a Brisbane judge says.

Jenna Louise Driscoll, 27, will be sentenced on Monday after pleading guilty to the acts, drug trafficking, stabbing another woman with a fork and, on two separate occasions, biting a child.
Judge Terry Martin made the remarks during sentencing submissions on Friday in the Brisbane District Court.

Defence barrister James Godbolt said his client had been affected by the public shaming of the bestiality charge and had stopped physically attending the University of Southern Queensland.

"It might be a sad reflection on society that the bestiality attracts more publicity whereas the serious offence of trafficking cannabis does not. It rather undermines the factor of general deterrence," Judge Martin said.

The court was told Driscoll ran away from home when she was 16, started a relationship with a man 12 years her senior and started smoking cannabis when she was 18.

Video of the bestiality was found by police following a drug investigation in October 2014. The stabbing occurred in late December that year while the biting charges arose in 2015.

She was 24 when arrested for trafficking and bestiality, and was also on a good behaviour bond for a minor drug offence and obstructing police.

Prosecutor Dzenita Balic told Judge Martin that there were "three acts of sexual intercourse" with the dog.
"It seems it was in connection to the attempted arousal of her partner," Ms Balic said.

The prosecution said Driscoll had 15 regular customers and six suppliers and also a phone purely for the purpose of selling drugs.

Mr Godbolt asked that his client being given a head sentence of two to 2½ years, with it suspended.

"The trafficking is at the bottom end ... to support her own use of the substance," he told the judge.
"She is not living the high life."

He said Driscoll works as a waitress and had submitted to a recent drug test to prove she was no longer addicted to cannabis.

Judge Martin said he needed the weekend to consider sentencing, taking into account the public shaming of Driscoll.

She burst in to tears when told she would be spending the weekend in custody.
