Solitary confinement is not training the dog it is abuse!

Another day and another trainer recommending solitary confinement (guess what always the same company). I know I sound like a broken record but it really upsets me to see these dogs suffering.
Solitary confinement is abuse and in a human context considered torture.
I consider it abuse and torture in a canine context. It is wrong and does not help train the dog.
Dogs do not do the wrong thing because they are ‘dominant’ and want to take over the world. In most cases dogs do the wrong thing because they have not been trained properly.
So stop the abuse and just train the dog!
