A female jogger sustained at least eight deep puncture wounds after being attacked by a bull terrier which clamped onto her knee.
The dog had bitten another victim previously and had been made the subject of a strict muzzling order five years before.
Owner Debbie Bennett had taken the Staffordshire bull terrier out for a walk without its muzzle on the morning of the savage attack.
She was ordered to pay £600 compensation to the injured runner after she was hospitalised with her injuries and given a tetanus booster.
Bennett was also placed under social work supervision for 18 months, but was praised by a sheriff for having the dog put down in the aftermath of the incident.
The 34-year-old admitted failing to comply with a dog control notice imposed on September 4 2014, which banned her from having a dog without a muzzle, on February 23.
She also admitted that in Pitlochry that day, she had a dog which was dangerously out of control and bit a female.
Depute fiscal Mairi Graham told Perth Sheriff Court: “At 7.30am (the victim) went out for a run and was heading to Pitlochry Dam. The dog suddenly jumped on her, biting her knee and locking on.
“The accused shouted at it to let go and took it by the collar. After several seconds the dog eventually let go of the leg.
“The accused admitted the dog was to have been kept on a muzzle.”

The court heard Bennett pleaded with the victim not to report the attack, but walked off without muzzling the animal.
Ms Graham added: “She had at least eight deep puncture wounds around the knee. The dog had broken the skin and drawn blood.”
Bennett contacted the police, told them about the incident and asked what would happen as a result. She immediately took the dog to the vet to be euthanised.
She said the muzzle had broken the previous evening and she had taken a chance to walk the dog without it as she thought no-one would be around.
Solicitor Pauline Cullerton, defending, said: “This was the second such incident. The first was before she took control of the dog. She took it as a rescue dog.
“She realises it could have been avoided – it should have been muzzled – and she is keen to make compensation towards the victim.”
Sheriff Gillian Wade said: “Had you not had the dog destroyed I would have had no hesitation in making that order myself. I give you credit.”
