Is it cruelty or just discipline?
He is facing cruelty over a pig or something, not for his dog training, I don't remember. That being said, those in the Veterinary community don't like him. I have actually had several discussions with Vets, including an actual Board certified Veterinary Behaviorist, and they all say his methods don't work, and actually cause more problems, although I do enjoy his tv show.
I would have to see what he is charged with.
Anyone can make charges. Proof is more difficult to see.
I saw him wrestle a dog to the ground to assert his authority- I don't like him and I feel an investigation is in order.
I was on a farm once and saw how they killed the pig for slaughter, they hung him from his legs upside down slit his throat to bleed out, that to me is cruel.
His aggression could be the result of his wife dumping and divorcing him?
