Anna Firth, MP for Southend West, is aiming to introduce a new law to criminalise fatal dog-on-dog attacks.
Firth formally introduced the bill at the House of Commons this week after she launched a campaign following the death of a bichon frise in Leigh, Essex.
The bill would mean the owners of the dogs involved in fatal attacks could be prosecuted.
Firth said: “It is frankly scandalous that irresponsible dog owners are currently able to shirk all responsibility when their dog fatally attacks another, creating untold distress and harm to the deceased dog’s owner and wider family.
“Of course, not all dogs are dangerous and not all dog owners are irresponsible, but it is crucial we have accountability under the law so justice can be pursued.”
The bill will have its first reading on 23 May.
