Because you are insisting on warping my words...I used the collar for BARKING. The dog barked excessively when I left, which made it hard to work on behavior modification (which works, as shown by your articles and mine...as in why would you need behavioral modification in pharmaceutical studies if they aren't important...we can all agree on that at least yes?) It was the behavioral training and positive reenforcement for being quiet (aka bones, stuff to do, independence training with toys) that significantly improved his behavior. Because I will only address claims that I have made, not that you are trying to claim I made...1st Paper-http://www.shakewaggleroll.com/SiteAssets/articles/Clinical%20signs%20caused%20by%20the%20use%20of%20electric%20training.pdf

I found the PDF instead of linking science direct. So, this paper talks about, though shows the data VERY poorly (can you say chart anyone?), the use of shocking for aversion, lack of recall, and a very important control...random (also sad but necessary). There is a low number of dogs, which I complain about and acknowledge as a weakness, but the breed, training, handling, and methods of data collection and analysis are scientifically sound. The take home message is if you don't have a specific stimulus, aka barking, to directly elicit the specific response from the collar independent of handler, aka shocking from a shock collar, then you can have confusion and stress. Shock collars are in fact, able to overcome that...which of course is alluded to but enforced in later papers. There was a paper specifically addressing it...but it is in I think dutch...and I don't have my friend here to translate for me. =)

2) This is from a very good journal...http://www.biomedcentral.com/1746-6148/8/93?fb_action_ids=235011813306543&fb_action_types=og.recommends&fb_source=other_multiline&action_object_map=%5B10150970539591927%5D&action_type_map=%5B%22og.recommends%22%5D&action_ref_map=%5B%5D And discusses different types of training. Yes, positive training is better, which I used, as is training classes and behavioral modification...but again that was for the anxiety, not the barking. Barking was solved by the shock collar. Solid stats. Solid numbers. Solid balance with all available training methods. Again, I have never said there is only one option...this talks about may options for dog training. I like the balance.

Regarding efficacy, since the drugs are not showing that...this...http://www.sciencedirect.com/science/article/pii/S0168159113001020...discusses efficacy of shock delivery for aversion. It also indicates that a warning sound, like the one my collar uses, could overcome animal welfare concerns as the long term aversion to the stimulus is strong. The drawbacks are well outlined, as are the stats. It isn't perfect, but it is nice.

This paper -http://www.ingentaconnect.com/content/bloomsbury/azoos/2002/00000015/00000001/art00005- discusses the use of negative reenforcement and punishment supplementing positive reenforcement. If you cannot read the article, let me know and I can get behind the paywall tomorrow.
