At what age does a mixed-bred dog become naturally protective of it's home?
Also, it's fenced-in yard? One is a Shep/Rotti and the other is a Shep/Hound. Both are about two years old, and so far, are very friendly. Will they ever become protective, since they are already two years old and show no signs of aggression?
I want people to think the dogs are aggressive, whether they are or not, just by barking at them, at least.
