Ok, I am beginning to understand where you are coming from. You tried an alpha roll on a dog and it didn't work. You tried other ideas gleaned from Cesar and they didn't work for this particular dog.
That doesn't make all of his methods wrong for all dogs. It simply means that his methods didn't work for this particular dog.
One of the most valuable pieces of training information I gleaned was once again from a horse trainer who told me..... If it doesn't work try something else
Don't keep doing the same thing.
