I’m writing to let you know of some really dreadful misinformation going around.
But first, here’s the truth.
It’s very simple. Prong collars hurt dogs. They can hurt a lot, depending on how tightly they are fastened and the handler’s behavior. Sometimes the sensation may be as low as mild discomfort. But make no mistake: if wearing a prong collar gets your dog to stop pulling on the leash, it’s because it becomes uncomfortable to do so.
If you take a good look at a prong collar, your intuition will be correct. Ouch! Even though those prongs are blunt,
Please see the additional note at the bottom of the post.
Prong collars, also called pinch collars, are metal chain collars for dogs that include links of prongs whose ends press into the dog’s neck.
When a dog pulls on leash, moves out of position, or is “corrected” with a quick snap of the leash, force is exerted on the dog’s neck through the points of contact of the prongs.
Elicited Aggression: If you hurt or scare your dog, she may hurt your other dog or your kid.
Generalization (related to #1 and #2 above): If you scare or hurt your dog, she can become afraid of (or aggressive toward) other things associated with your actions, like locations and objects.
Conditioned Suppression/Learned Helplessness: If you hurt or scare your dog a lot unpredictably, she will live in a state of fear and also may not do much of anything.
Injury: If you hurt your dog you could cause him injury.
Reinforcement of the Punisher: If you hurt or scare your dog regularly, your actions will easily be reinforced and become habitual. On the occasion that your actions don’t work to interrupt or decrease behavior, you will tend to escalate the hurt.
Copying: If you see someone training their dog through pain or intimidation, it can influence you to do it yourself.
These are the things you risk if you use pain, fear, force, coercion, intimidation, or even startling to train your dog. The effects are not limited to training “tools” such as are featured in the picture below.
Not all of them will happen all the time. But they are all possible, and we can’t know ahead of time which dogs (and which owners) will be strongly affected by the use of aversive methods.
That’s the short version. For scientific references, check the resource page described and linked below.
This resource page cites articles, most of them classics from peer-reviewed journals, on the above types of fallout. It is provided for people who need or want to investigate the original sources.
Most types of aversive fallout are so well documented that the reader can check out the original article and follow a cascade of research following it.
Besides classic sources for the above effects, I’ve listed the main studies that document side effects of painful or scary training for dogs, and also a couple of other important references. Like many of my projects, the page is ongoing.
