Comment 'Here is an article a...' to 'HELP!! New Caucasian Puppy'

Here is an article about the Orijen dog food you asked about http://www.dogfoodadvisor.com/dog-food-reviews/orijen-dog-food-adult/

Also, I have not tried clicker training but there was/is a member here (http://molosserdogs.com/Kat )who use that method with her Caucasian with great success. Try to get in touch with her through the site I am sure she will discuss it. There is also some discussion posted in the forum by her.
