Shelley Crutchley's pet Babe was not on a lead when it attacked the other dog during a walk in Biddulph.
The Sentinel reported how greyhound Jaz needed 300 stitches following the incident in August.
Crutchley, of Congleton Road, Biddulph, pleaded guilty to being the owner of a dog dangerously out of control in a public place when she appeared in court.
Magistrates have now fined her £190 and ordered her to pay £150 compensation to Jaz's owners, Carole and Stephen Ryles.
Mrs Ryles says she has needed counselling because she suffers from flashbacks of the attack, while Jaz may still need more surgery on her wound.
The 62-year-old, from Biddulph, said: "We are happy with the outcome of the court case. The owner has been told to keep her dog muzzled and on a lead in public places.
"All we wanted was for the dog not to be able to do it again. The lady was upset about what happened and she did come into the vets and show concern about Jaz. But she has not been through what we have.
"I can't even begin to say what we have been through. Even now I'm having to see a counsellor because I can't get the flashbacks out of my mind. I relive it all over again, it was so terrible."
Jaz was attacked as she was being taken for a walk on her lead near Biddulph Valley Leisure Centre, off Thames Drive, Biddulph, on August 9.
The English Bull Terrier ran up to her and grabbed her by the neck, leaving her with a gaping wound as well as punctured muscle, a broken tooth and a damaged tongue.
Mrs Ryles said: "After the attack my husband and I spent three months sleeping in shifts so one of us could be downstairs with Jaz all the time, because she was so poorly. The wound has only just closed up. She is much better now and can go out for walks, but she's now terrified of other dogs and she will not go past the spot where it happened.
"She has done really well to get to where she is now, but it has taken a lot of love and attention to get her there.
"My opinion is that all dogs should be kept on a lead in public places, no matter what breed they are, but people just don't do that."
Mr Ryles, aged 61, added: "I have more or less got over what happened now, but it has been very traumatic for Carole. Jaz has recovered well but she's frightened of other dogs. We are just glad the court case is over and we can get on with our lives."
