Seriously, I have a question from some of you who are experienced in the intuition that dogs exhibit in relation to human behavior. We all know about their abilities in scent, etc. But what I am wanting to know is do you believe they have a sense about people who are unstable, be it neurological or alcohol/drug induced? I realize that packs in the wild will extricate or even kill their weak and unstable members. Do they sense this in humans and further react?
I think most of those on this forum know that I have had German Sheps for nearly 50 years with having had nearly 200 rescue GSDs & a few DSs thru here in the past (not anymore). Not once have I ever had a situation where one of the dogs bit anyone, not one time. I would always circumvent any possibility though.
We have lived in the same home now for 24 years and have a neighbor who is mid 60's, mentally unstable, a serious hoarder and a nosey body.

She has started frequently coming over which disturbs me and my family but we try to be cordial. Last month as she was leaving, my little cattle dog took a nip at her heel but no bite. A heeler, so this is her nature, right esp since I do herding with her. Then last week, the neighbor bangs loud on the kitchen window where I was cooking supper and I went to the front door to let her in to get some ice (she doesnt have a frig) in an igloo. <GRRRR!>

She is loud and obnoxious type, as wide as she is tall at about 5'. The GSD met her nicely as she greets everyone, but the neighbor barely made it in when the heeler nailed her on the outer thigh. I mean a full bite but only one small slight puncture wound, no blood tho.

Schutzhund folks would be impressed BUT......I was totally caught off guard, blown away! This little heeler goes everywhere with me, loves all people, all dogs, critters, lets the grandkids wrestle and share their food. A real sweetheart. Very smart, great companion dog.
Now, do you think she recognizes this woman is 'touched'?? Did my heeler recognize the stress this person induces on my home or do they have an extra sense about mental unstability in humans?
I know this is not about my DS, but it just as well could be but I know she is not trusting so I alleviate any potential scenario with her. I thought I could read my dogs well and evidently I could use some input. What do you all think?
PS: The neighbor came over a few days later, pulled down her pants in my front yard to show me the bruise!!! Yeh, she IS definitely touched!!!
