Well said Emma. I agree that the dangers & pitfalls of using ecollars are too high to be disregarded, both from a welfare perspective & the efficacy of the intended results.
One of the dangers of using ecollars is how to predict the level of pain & shock for
that particular dog. Peoples & dogs pain thresholds & perception of physical pain are very different & can also vary within an individual person or dog depending on their arousal or emotional state at the time the shock is administered. How on earth does anyone judge the appropriate level of pain that is needed in each instance to achieve the intended result? It has been suggested that you start at the lowest level & gradually increase the intensity of the pain until the dog reacts. By the time the dog reacts, how can you be sure that you are punishing the exact behaviour that you want to stop?
For instance a dog that is intent on staring at sheep, & is about to run at the sheep ~ at what stage & at what level do you administer the shock? Too low & it is ignored, a bit higher & the dog may flinch, may be temporarily distracted but continues staring, so a bit higher, may be more of a flinch, plus heart rate increases, stress levels increase, so an even higher shock, & suddenly the dog yelps in pain, spins round & stops staring at the sheep.
Now how on earth is the dog supposed to know what it is being given the electric shock for? For staring at sheep? No, because it had been staring for some time & nothing happened. For staring at sheep for over a minute? How does the dog judge this? For ignoring the owner's recall command? For momentarily shuffling a foot ~ a movement that had gone entirely unnoticed by the person administering the shock? Or perhaps the sheep moved at the time of the painful shock so did the sheep moving cause the shock? Perhaps a loud motorbike went by at the same time? Or someone opened a squeaky gate? These spurious associations are completely outside the dog trainer's control & yes, the sheep staring stopped but how can you tell if the dog has made the correct association between its own behaviour & the pain or cessation of pain? Other than doing it again, & again, & again!!!
So the alternative is to inflict a high level of shock immediately in the hope that you target the behaviour you want to eliminate/punish. That's not kind, that's deliberate cruelty in my book, the same as hitting a dog, jerking at its neck, kicking it etc. The only difference is that, if you're lucky, you will be far enough away from the dog so that it won't associate you with the shock!
Even used by an extremely experienced dog trainer, it is difficult to give the right level of shock, for that particular dog, in those specific circumstances & at the exactly correct time. You only have to look at all the things that could go wrong for the experienced dog trainer to see the disastrous consequences that are likely to occur in the hands of an inexperienced person
.
The article for which Emma provided a link, & a later study by Schalke (Uni of Vet Med, Hanover 2005), conclude that the dogs were adversely affected by the shock long after it occurred, heart rate & salivary cortisol (used as measures of stress) rose just at the presence of the handler & that the use of electric shock is not consistent with animal welfare.
I appreciate that some dog owners are at their wits' end & will have tried every other method they can think of (or have been advised to try) before resorting to the use of an ecollar. Sometimes they are on the brink of rehoming the dog, or having it pts because of the behavioural problems. So I can definitely see the attraction of trying them ~ last chance saloon!! But this doesn't make it kind, or right, to use them, either in the short term or long term.
Predatory drive can be very high in some dogs & more prevalent in certain breeds. Maybe owners should be advised of this before they get the lovely little Border Collie pup that they've always promised themselves on retirement! It's all very well saying that the predatory behaviour should be redirected onto a tennis ball or whatever, but I've seen some BCs who have developed OCD in relation to tennis balls ~ not a mentally healthy obsession at all! But even if you choose to go down that route, surely you'd condition the obsession with tennis balls long BEFORE you allow the dog any contact with sheep ~ not after the event when the dog is now fixated on sheep so the tennis ball is completely overshadowed by the sight of sheep ~ so there would be no need to use an ecollar.
I don't care how many very experienced trainers have successfully stopped unwanted behaviour by using ecollars, the dangers is, that if they are available on the market for any dog owner to buy, they will contnue to be used wrongly & painfully for many poor dogs. And even if unwanted behaviours stop, where are the studies to show that everything else in the dog's life is still happy, that it still feels the same way about its owner/trainer, that it is still the responsive, outgoing dog that is prepared to give anything a go?
