That Lincoln study was a terrible piece of science. It's been demolished even by positive trainers. I'd provide links if I was on my laptop but I'm not, not likely to be till late pm.
An e-collar, well used, can be amazing. I know a dog who is off the longline because his owner was able to resolve recall issues with an e-collar after a year of failure with positive reinforcement (rescue dog). I know another rescue, recall also resolved the same way. Both dogs are confident and happy, not anxious and terrified. E-collar training has given them freedom.
The BSAVA's own behavioural manual says that the prognosis for fixing livestock chasing is 'only fair' using the methods they recommend - positive reinforcement only. Yet you have e-collar trainers resolving livestock chasing routinely with sensitive and sensible e-collar use. With stock, it's not as simple as keeping the dog on a lead in a field with stock (which is what you should do anyway). Leads get yanked out of hands, sheep escape onto footpaths - shit happens.
I know I'm in a minority here, but I'm not celebrating the removal of a valuable training aid.
And I expect most or all of you damning them have never felt one on your own skin, or seen one well used.
