Mrs Layton appealed her disqualification in December 2014 and in March 2016 and both were subsequently rejected by TCDC's judicial committee. Desperate to own a dog again, she then lodged an appeal in April 2016 at Thames District Court.
An appeal conference was set at the court but was adjouned after TCDC realised incorrect information about how long Mrs Layton had been banned for had been put in reports which the committee had used to consider the earlier appeals.
The reports had incorrectly stated Mrs Layton had only been banned from owning a dog since April 2014 when she was actually disqualified on October 2013 so had served an additional six months.
A third committee hearing was instead held on 2 June and this time the committee voted to lift the animal lover's ban.
TCDC community environment group manager Barry Smedts said, in a statement, there had been a turning point because Mrs Layton had demonstrated accountability for the circumstances leading to the offence involving her dog.
"Given the changes demonstrated by the person, and that steps will be taken to ensure measures are in place to fully train and secure any future dog she owns, it was resolved to immediately lift the disqualification."
Mrs Layton said she cried all day after hearing she could finally own a dog again.
She received the formal letter from council last week confirming the ban was lifted and immediately went and paid a deposit for a black labrador puppy. Mrs Layton is now counting down to the start of July when she can take the puppy called Bojangles home.
"It's been hell on earth. I've got two cats now and they've been a replacement, but it's not like you can take a cat for a walk. And that's what I've missed."
Mrs Layton said she had been unlucky with Boris.
"I've owned dogs all my life. It was just a one-off thing. We made mistakes, we paid the price. It cost me $10,000 and it's over now and I just want to start again and be normal again."
Mrs Layton told the Herald in 2014 that Boris was "boisterous and large" and argued whether it was even an "attack" because he had not drawn blood.
