Totally agree Xamen. Would be hugely disappointed if the dogs showed genuine protection ability only on the premises. Don't think this will be the case though. These are some of the things I want to test for. With my dogs and those of friends and breeders I have spoken to, it certainly appears that Mastini develop guarding instincts at home and in the garden at a comparitively young age and take longer to develop these same instincts on strange turf. My 9 month old b1tch doesn't have these instincts off of the property so far but is very guardy at home. My 2 year old male is very protective both at home and outside on walks or in the woods.
