There is a lot going on on this thread and I want to respond to it. This is going to be very long.
Does aversion cause pain or fear? It certainly can. The e-collar, well used (and it sounds as if @KeenOtter went to a terrible e-collar trainer) can be a very subtle and effective piece of kit. Since we last went around this topic a year ago, I have begun to use them on my dogs. I had a dog I could pull off prey with a squeaky toy, as long as I was able to react before she really got going. So, in some areas, at some times, I kept her on a longline while still working on the recall with the ball. One day she unexpectedly put a hare up, yanked the lead out of my hands and was gone (“stupid owner”, no; “management never fails”, also no). I have another dog who is just a hunting machine, doesn’t give a shit about toys, doesn’t give a shit about food - not compared to something with a heartbeat that she can chase. Same breed, but tougher to train. I considered their needs and our environment, and went to an e-collar trainer.
I would say that the highest shocks my dogs’ collars deliver are unpleasant. Is a high shock painful? Yes, but fleetingly. Is it very painful? No. They are very brief, and any sensation fades incredibly quickly - I know this as I have tried the maximum setting on the tender skin inside my forearm. I very, very rarely have to use them at more than a low setting: my older, bolder dog works at about 8/100, which as a PP said is like an ant walking about on you (maybe a stick insect, but you get the idea). The younger one, who dislikes loud voices, needs a slightly stronger stim. This surprised me, but I was careful with both dogs to habituate them to the collar and find their working level. I went to an experienced trainer. Have I been perfect? No. Have I fucked my dogs up? Also no. Are they, the wildlife and the livestock safer? Immeasurably so. Do my dogs show stress when stimmed? Almost never, and they both recover extremely quickly (within a few seconds). How often do I need to use the collar to stop chasing now? Hardly ever now. Rabbits today, no problem. Muntjac and pheasant as previously mentioned, no problem. Sheep? I heeled them off-lead through sheep a week ago, literally 2 or 3 feet away, with the owner’s permission. Were they scared of the sheep? No. Were they a little cautious of the sheep? One was; the other was mildly interested. Were the sheep safe? Yes. Would I ever off-lead heel them through a random field of sheep along a footpath? No. Because farmers have enough to worry about without seeing off-lead dogs in a field of sheep. Because, like management, training can fail. I have known a wonderfully well-trained trialling dog who, during a trial, tanked off over the horizon after a hare.
We’re always told three things with prey driven dogs: ‘keep it on a lead’, ‘manage it properly’ and ‘don’t get a dog you can’t control’. Keeping it on a lead, as my own experience indicates, is just not enough. It’s not enough because leads get yanked from hands, or break. God knows, I’ve seen enough videos of dogs chasing livestock with their leads flapping behind them. It’s also not enough because some breeds are extremely athletic and need to run, or need off-lead exercise to flex their drives and their mental muscles so they don’t go crazy and wind up bonkers and medicated (I am not, FYI, saying that all bonkers and medicated dogs end up that way due to lack off-lead exercise). As I said before, an enclosed paddock would just not do it for my two - never mind the cost and the travel.
Management fails. The hare was where a hare shouldn’t have been; my grip on the longline wasn’t as good as I thought it was. You turn a corner, with the sheep safely the other side of what looks like good solid stock fencing, and there are two sheep and a lamb, out in the middle of the track. You walk through the local park and a muntjac literally jumps over your dog. That was my local park. There is literally nowhere I can walk around here which is definitely free of all rabbits, hares, muntjac, roe, fallow, pheasants, partridges, sheep, horses and cattle.
‘Don’t get a dog you can’t control’ is sensible advice, until you get one you thought you had under control and find that some things (hares) tip her over the edge, or you get one (like my younger dog) who has much more predatory drive (and game-finding ability) than you ever anticipated.
I can now control properly my dogs. They have huge amount of freedom. We have a great relationship. I love walking them. I know three other local dog-walkers who also use e-collars, two of them with rescue dogs, whose relationships with their dogs have been transformed by e-collars: ‘I can let him off more, and he’s happier.’ ‘She’s off-lead more, because she comes back and I am so much more relaxed, and so is she because I’m not stressing at her.’ ‘I honestly, when he broke my finger when he yanked on the longline that time, I thought, I’ve just had enough, I can't cope. But now…! Look at him! Good boy!’ I paraphrase, but you get the idea. All of us went to e-collar trainers: we didn’t just slap the collar on the dog, we habituated them and found their working level.
I resent being told that +R is everything (and made to feel inadequate) by people who, it turns out, have to keep their dogs on-lead or minutely manage where they walk them because they cannot be off-lead safely around wildlife and livestock. I also resent having the science thrown at me, when so much of the science is poorly designed (see my earlier comments) or inherently weak (based on surveys; extrapolates sub-populations over the whole canine population; tiny samples - there was a paper recently on +R for resource guarding, referenced by Zak George with a sample of FIVE of which two were lost to follow up). I may be ‘some random on the internet’ but Jo-Rosie Haffenden is not. You can ignore what she has to say (and she’s not the only one saying it) and believe the science if you want, but I read the science very critically, and will continue to do so.
If you can train your high-drive dog 100% +R to do everything it needs to do, to never chase, to never follow a scent and not recall, then fantastic, well done. And I hope you never get a dog you can't control.
I could go on, but this is crazy long.
