Mother wrestled dog to protect children
Elsewhere, a dog that apparently savaged a family pet leaving children shaking in fear has been seized by police.
Officers seized the Dogue de Bordeaux Boxer cross in Woodmansterne Road in Carshalton on Thursday, January 16.
The seizure came following a report that the dog had ran out of a home and attacked another dog that was being walked by a woman and her three children on December 31.
The attacking dog sank its teeth into the family's smaller dog causing the children to scream and run to hide in a nearby driveway.
The mother wrestled the angry dog and held it still in case it attacked her children and after three to five minutes a man came out of the same house the dog had run from and took it away without uttering a word of apology.
The woman took her children to their home nearby and told police they were shaking in fear after the incident.
Their dog had four deep puncture wounds to its groin, two wounds on its left side, bruising on its side and stomach and wounds on its paws.
The mum had treatment, including a tetanus injection, for a wound on her hand.
The seized dog's future will be decided at a court hearing for which a date has yet to be set.
