Electric collars that shock wayward cats and dogs into submission have been banned for the first time in Britain.
Wales has become the first part of the UK to outlaw the use of collars, which deliver a shock of electricity to the animal's neck.
Some are activated by the owner, who simply pushes a button on a remote control when their pet misbehaves.
Owners who break the ban face a fine of up to £20,000 or six months in prison.
Pet welfare groups, including the RSPCA and the Kennel Club, say the £100-plus electronic devices cause unnecessary pain and suffering and want the ban extended across Britain.
But some experts say the technique can improve the behaviour of dogs that would otherwise be put down, train excitable pets to stop running into traffic and stop them from worrying sheep.
'Actually, the electric collar was bought for our dog. But it's useful if Henry's sermons go on too long.'
