Measures to deal with out of control dogs have been welcomed by the Communication Workers Union (CWU).
The draft Control of Dogs (Wales) Bill is intended to provide better protection for the public and will leave England as the only part of the United Kingdom without updated dogs laws, according to the CWU.
The union said nearly 5,000 postal workers were attacked by dogs in the UK each year and that 70% of those took place on private property.
Billy Hayes, CWU general secretary, said: “We’re really pleased that the Welsh Government is taking the issue of dog attacks seriously and taking positive action to help prevent dog attacks and deal robustly with irresponsible dog owners.
“England will soon be the only part of the UK without updated dogs laws as Wales is following in the footsteps of Scotland and Northern Ireland by introducing new improved legislation.
“It shames Westminster that all devolved institutions have taken action on dogs laws while the government has procrastinated and steadfastly refused to act on the issue of dangerous dogs. All this time people continue to suffer serious injuries and lose their lives in dog attacks. Westminster should follow Wales’ example and take action to overhaul failing dogs legislation.”
