You can absolutely use this method to work with aggression as the clicker sound goes though the reptilian part of the brain and will over ride the reaction of aggression and change it from within.
Where as the other suggested method stops the brain form learning and working and does not do anything but teach learned helplessness.

It is the best method to work training with dogs, that is out there right now.

Also as it has been well studied in animals of all kinds and found to be the most effective method of training it is being reworked in the form of Tag teaching to work with athlete's and autistic children. They are finding great impovement faster.

You are so on the right track and I hope you continue to enjoy your growing partnership with your dog and relationship of mutual trust and respect and kindness grows. For a true working partnership is a great thing to experince and to watch a dog experiment to see what he needs to do to get that clicker to go is a wonder to see. What you can do is look into 100 thingsto do with a box ideas and watch what your dog will come up with. It is a blast.

I love seeing dogs brains in full working order.
