Ministers will say that compulsory microchipping will ensure that all dogs can in future be traced back to their owners, who will then be held accountable for the animal’s behaviour.
There have been growing calls for the Government to take action amid concern from animal charities about dangerous dogs being used as weapons and status symbols.
Under the measures to be unveiled by Owen Paterson, the Environment Secretary, dog owners will also now face prosecution if an animal attacks anyone in their home.
Those plans will be welcomed by postmen, who have campaigned for a new law ensuring that dog owners are prosecuted even if their dog attacks someone on private property.
