The maximum sentence faced by dog owners whose animal kills someone in England and Wales could be raised to life in prison. The Government is launching a consultation - asking people for their views on dangerous dogs.
Currently the penalty for the owner of a dog causing injury or death is two-years, an unlimited fine, or both.
Jim Moran spoke to BBC Breakfast about his experience after his guide dog, Carlton, was attacked by a bull terrier.
