It is actually refreshing to find someone breeding protective dogs and not making apologies for them.  I think that because of social, governmental, and breed club pressures, most once formidable breeds are not relegated to coach warmers, status symbols, and ribbon magnets.  Not good for any breed but especially the breeds with some fire drive to protect.

Your ownership of one of these dogs and the learning you achieved through that process are what makes a great dog owner.  Keep up the great work.
