That said, there really is no need for a shock collar or prong collar unless you don't want to put in the time to shape or capture behaviors. They might work, they might not harm a dog long term, but they are always the lazy way.
We chose to save an 8 yo fox terrier mix from an LA shelter about 4 months ago and brought him north to live with us. He is super reactive with larger dogs and we have them. Life has been hard, but he is making progress. Sometimes we break out the doggie helpers.
The hardest thing to do is to remember to give him something very yummy when he is sitting near one of the larger dogs and NOT barking, reacting, being all worked up. It took years of training, much of it with Kathy, to train myself to remember to do this. The average dog owner does not put in that kind of time and effort. We pretty much live our dogs, quite a few are slowly overcoming serious behavior issues. These behavior fixes take time and don't happen with one or two corrections on television. This is the most damaging thing Cesar does, makes people think you can quick fix a dog by terrorizing it. Dogs ( and humans ) don't learn under stress and in a state of fear. So it doesn't stick.
The other thing is that I think more dogs bite than you think. I spend my "other" time in a hospital and we see a lot of dog bites. Jean Donaldson says she thinks many of them go unreported. Have you read Culture Clash? I bet you would like it.
And there are those who consider training with treats “lazy”.
You can’t win.
It’s like training dogs by committee.
If you had spent 24 years with sight hound rescue like I have, there are a LOT of grieving owners who wish they’d had a “lazy” e-collar on their [former] dog.
Life or death situations arise in a millisecond with those breeds.
I don’t care if you’ve trained a sight hound to a CDX or not...when a squirrel runs, they -will- chase it.
It’s wet-wired into them.
On this, we’ll just have to disagree.
I can only state what I have experienced personally.
Anything else is a theory, until I have lived it.
I much prefer Dobe rescue.
*Most* of the time, they stop and come back.
Makes life a lot less stressful.
