Great news is afoot!
Shock collars are to be banned in England:
Electric shock collars for pets to be banned - www.bbc.co.uk/news/uk-england-45320038
Wales and Scotland already have bans coming but I don't know about Ireland / NI.
I saw two dogs at a campsite last week with shock collars on for barking - sadly their owners had been advised to use them by a behaviourist.
However, their friend was also a dominance theory trainer (as in don't let dog sit higher than you, don't allow dog to eat before you do, don't give a dog a cuddle variety) so I guess they were getting mixed advice from confused sources.
Any thoughts?
