I love dogs. I always make friends with them at the home inspection, unless the dog is not into it, or is over-protective. I squat down low, talk in a gentle voice, and let them sniff my hand. Once they smell a stranger, they can decide if they want to be pet or not, and I don't push it. Most times, I make a friend.
Today, I was in a house in Amityville, NY and there were two Rotweillers in cages in the yard. These dogs were dying to get a piece of me. The owner stated they only will be friendly towards family members. I asked which junkyard they spent their days in and was given a look that said "what do you mean, these are our family dogs".
The neighbor spoke to me as I left, and she hated these dogs. One reason - she has children and she fears for their safety. She told me they trained these dogs to be that way.
I understand the need to protect what is yours, but this is extreme. Suppose one escapes. What if a fireman is attempting to save a life or put out a fire?
Maybe its me, but I think this is well beyond the normal realm of thought for dog obedience. This is like training a killer to kill.

Some humans are too stupid to deserve to have animals of any sort. It is unfortunate that there are not licensing requirements or competency tests to become a pet owner.
