My son, 10, was savaged by out-of-control dog while playing football

, said: "They had been playing for half an hour when they saw the dog as Giorgi was taking a shot at my other son. The dog came running over and popped the ball.

"Blake, who has autism, was quite angry that it had popped the ball. So he walked off the field to find an owner.

"But before they had even got off the field to the footpath, they heard a scream, and they turned round to see the dog attacking Giorgi."

She added that the dog "wouldn't let go" and that its jaws had to be forced open by a brave bystander with a paint scraper.

The dog then tried to attack Jimmy before it was chased off and the boys were brought home by a local man named Dean, according to the distressed mum.

Giorgi was rushed to the hospital on February 14, where the extent of his wounds became clear.

Kimberly recalled: "I said to Giorgi, 'Come in the house' but he said, 'I can't walk'.

"I initially saw the puncture wound on his left arm. But it wasn't until I got to the hospital, and they cut off his tracky-pants, I saw several bite wounds to both sides of his legs."

The young lad sustained a puncture wound to his right elbow, three or four deep cuts on his left arm and bite marks on his legs.

He went under the knife for plastic surgery to repair the damage on February 15 and remained in hospital overnight.

His mum called for tougher restrictions on dangerous dogs, saying: "There needs to be tougher laws around dog ownership, and if you are found responsible, you need to respect the consequences.

"Sorry is not enough. I could never forgive myself if it was one of my dogs that had gone and bitten not just one child but two children and caused significant injuries.

"Owners need to be more accountable. Giorgi hasn't been back to school yet. He is stills scared, and he won't go back to the football field."

Jimmy also received treatment for his less severe injuries.
