A woman suffered serious arm injuries when she was attacked by a dog, believed to be a rottweiler which had broken into her garden.
The attack happened the day after Archie-Lee Hirst's death
The 26-year-old was taken to hospital after being attacked in Fisher Street, Brierley Hill, in the West Midlands.
Police said two dogs taken from the scene were later destroyed.
The attack on Saturday happened a day after one-year-old Archie-Lee Andrew Hirst was killed by a rottweiler at his grandparents' home in West Yorkshire.
Archie-Lee suffered multiple injuries on Friday when he was mauled by the dog, which was a family pet.
A 30-year-old woman was arrested on suspicion of allowing dogs to be dangerously out of control after the incident in Brierley Hill. She has since been released on bail.
John Hughes, a neighbour of the woman injured on Saturday, spoke of how he heard her screaming before seeing the dog attached to her arm.
"We opened the gate when we heard her screaming for help," said Mr Hughes.
"The dog was attached to her arm. She was screaming and in pain."
Mr Hughes stepped in and grabbed the dog by its neck and shook it.
"My wife says it let go then but I ran to get a spade, in case it came back."
He added that he did not think twice about stepping in to help.
"I was conscious of the dog but I think anyone would do what I did," said Mr Hughes.
"You can't walk away and let a dog rip someone to pieces. You tend not to think of yourself."
