It's much more than a tap, you have to admit.
It may be but it's not abusive by any means.
Unless you've seen a fair amount of his episodes you have no idea the magic he works.
He does things that you cannot put down to any other explanation than a miracle.
I would never endorse it if I thought was cruel or abusive. He is not booting into the dogs with aggression.
Oprah Winfrey even swears by him, she has access to plenty of training methods and plenty of information. I don't think she would endorse something that creates fearful or aggressive dogs. Cesars techniques do the oppossite of this. The proof is clear in all his clients that have had their lives turned around for the better & his amazing pack of dogs that live in harmony.
Watch this episode of him making these aggressive girls submit,
You'll see him tap the dogs, but he definitely doesn't abuse them.
