‘The Sentencing Council issued a dangerous dog offences guideline in August 2012. In May 2014 amendments to the Dangerous Dogs Act 1991 were enacted through the Anti-social Behaviour, Crime and Policing Act 2014, which made such substantial changes to the offence and the maximum penalties that the Council considered it would be appropriate to revise comprehensively the existing guideline.
