A mother and her son have been banned from keeping animals after one of their Bull Terriers attacked a strangers pet dog in the street.
Nora Mannion, 46, of Denmark Street, and Sonny Mannion, 21, of The Oval, Oxford, owned five dogs.
An RSPCA inspector said vets found evidence the dogs had cigarette burns.
The mother was banned for 10 years and given a six-week jail term, suspended for 12 months. Her son was banned from owning animals for five years.
Nora Mannion was also ordered to pay £500 costs and £500 compensation.
She was charged with being the owner of a dog and allowing it to be dangerously out of control in a public place and cause injury.
Sonny Mannion was also sentenced to a three month curfew and ordered to pay £500 costs.
His charge was in relation to the duty of a person responsible for an animal to ensure welfare, pertaining to the Animal Welfare Act 2006.
Both pleaded guilty to the charges.
All the dogs had to be put down because they were too aggressive towards humans and other dogs.
Senior RSPCA inspector Kirsty Wignall said: I am pleased with the sentencing, particularly with the disqualification.
She said it had not been possible to prove who was responsible for the burns on the dogs.
The animals also had wounds indicative of fighting with other dogs or each other, she said.
