I have an 11 month old Rottweiler, as of this day I have only heard him bark 4 times. Is that normal? He won't bark at strangers or when someone walks by the yard not even at the squirrls that run through the yard. My friend who has a Rottie says that he will grow into it and that it sometime takes as long as 2 years before they start wanting to protect the house. Can you give me some advice on this? Thanks.
