A woman was left permanently scarred after a vicious attack by a dog that ran up to her while she was getting out of her car, a court heard.
The victim was getting out of her car in Grays, Essex, when Peter Fricker's unaccompanied bull-breed dog charged at her.
She was badly bitten, suffering eight deep wounds to her legs, and needed urgent surgery.
Police decided that the woman's serious injuries amounted to GBH and seized that animal under the Dangerous Dogs Act.
Officers described the dog as being aggressive and "of a dominant nature".
Following a police investigation, Fricker, 43, first appeared at Southend-on-Sea Magistrates' Court last year when he initially denied allowing his dog to be dangerously out-of-control.
This week, he appeared at Basildon Court, Essex, and was sent to prison for 18 months for allowing his dog to be dangerously out of control and causing injury.
Fricker was also banned from keeping a dog for ten years.
PC Jack Emerson said "We welcome the court's decision which reflects the danger posed by some dogs and those who fail to keep adequate control of them.
"We hope that this sentence sends the message to owners that whilst they are incredible pets, dogs can pose a risk if not properly trained and cared for.
"Owners must also ensure that they have adequate knowledge and capability and have the right environment to care for them."
The court also ordered the dog's destruction.
