Mr Clayton rushed to the aid of Sarah Porter and her six-year-old son, as she tried in vain to protect her chihuahua Beau from another dog.
The incident took place on Monday, June 2, at 3.20pm as parents were collecting their children from the four nearby schools.
“I was gardening at the time and I heard this screaming and was concerned what was going on as it was school time,” said Mr Clayton, 80.\
“I came out the front and there was this dog going like hell at this poor girl and her little dog.
“She was trying to hold the dog up as high as she could, but the damn thing kept jumping up and grabbing her dog. It just kept pulling at it, I’m surprised it didn’t rip it apart.
“It was a nauseating experience, and I’ve never seen anything like it in my life. I’m surprised none of the children ended up being caught by the dog too.”
Mr Clayton said he tried to protect Beau from the dog but was knocked to the floor, injuring his arm and face. He also received bites to his hand.
“I couldn’t remember much after that,” he added.
Miss Porter, who was also with a friend’s child at the time, said she was ‘terrified’ the dog would turn on the children. She received lacerations on her back in the attack.
Chihuahua Beau is recovering from her injuries. The other dog, thought to be a Staffordshire bull terrier, was destroyed at the owner’s request.
