This woman walks her dogs past my house at least a couple times a day and has done so for at least a few years, so I know that she knows my dog is there. I do have Beware Of Dog signs at either end of my fence. So with that in mind, that's just more of a precautionary measurement than anything, it still wouldn't absolve me of anything if she were to bite or hurt anyone. It's pretty dumb, but that's the way it goes.
I don't think following her home would be a good idea. That may lead into stalking/harrassing/intimidation issues. Even if she couldn't press charges directly to that cause, it wouldn't look good in other arenas if push came to shove.
As for training, I can't say she's great about it, but she mostly comes to me when I call her. On occasion, she'll get stubborn but that's usually when she's investigating something with her nose to the ground, but she'll come to me within about 15 seconds or so. Either way, it wouldn't have helped much as I was across the street talking to my neighbor. But I see the validity in your point, and I will continue to work with my dog to make that even better.
I like the security camera for several other reasons. Unfortunately, I don't know much about them. Can someone maybe point me to a good reference for just a single camera that I can maybe use my home computer to record to? Just a quick look around brought up entire systems (the smallest of which was a 4 channel setup with cameras and DVR for around $500) or just single cameras without any real info on how to use it. At least not to my uneducated knowledge. Hoping for something that's easy to set up, maybe I could do it on my own. Would you think that maybe a wildlife video camera might work? They only really turn on when there's movement. Or would I run out of recording space too quickly being in a city with plenty of foot traffic past my house?
Thanks for all the input and understanding so far. I didn't sleep well last night over this and its rather unusual for me to carry over such hostility and frustration after sleeping. If this is how I feel when my dog is "attacked" then I hate to think of how I would feel if it were one of my kids.
