Doing anthropology research on dog training - asking for advice/info/pointers

I wrote a bit about my work wiht my dogs quite a while ago, but since I have started sailing in the rough waters of what is college academics. Now I am trying to combine the two in what will hopefully be my senior thesis in anthropology which will take a look at dog traiining (more specifically on work with aggressive dogs, as I ahve to focus on something)

I'm not sure how many will read this, But I thought a post would not hurt, and I will appreciate all input.

So, here's the deal. While I was quite up -to-date with good (and bad) books and on who's who in dog training a few years back, I am not any more, and I am really craving input on where to look at for more information (what are the most controversial books/theories in the past decade or so, are there an statistics out there on how many dog owners implement which dog training approach - I haven't been able to find any, does anyone know of some good comprehensive studies on dog-owner relationships etc.). Finally, I am not from the US, but I'm trying to identify an area in the US (or a few dog trainers who implement different approaches) where I could do some primary research (I am, at the moment considering San francisco).

I would idealy love to do my research at a few places that offer dog training classes for owners, so I could talk to the dog owners and to the intructors about their experiences. are there any aggressive dog camps out there? Are there shelters that focuse on helping dogs with aggression problems find new homes?

Really any info would be helpful. My search at the moment is very broad, as I at the beginning of it (and I am doing a lot of googling and searching through a variety of journal article databases, but sometims jsut asking people does wonders in terms of info gathering)
