"The jury plainly did not unanimously share my view about the attack by the dog. Either way, the extent and number of injuries to the complainant show the dog took part for a considerable amount of time.''
That is the basis of Bayley's appeal to the Court of Appeal in Auckland, and she seeks to have her sentence reduced by about a year.
Her lawyer, Bill Nabney, said outside court today that if Bayley did not deliberately get the dog to attack then it could not be said to have been used as a weapon.
Therefore it should not be seen as an aggravating factor, he said.
Bayley still maintained that the dog did not inflict any of the injuries.
Referring to evidence from the trial, Crown lawyer Brett Tantrum told the court that Bayley had held Ms Smith down while the dog attacked her.
Bayley was capable of stopping the dog attack but she did not, he said.
Justices Robert Dobson, Patricia Courtney and Anthony Randerson reserved their decision.
