This was an odd choice for me to read, as I'm terrified of big dogs, and the barking of any dogs tends to jangle my nerves. But I enjoyed it, and feel like I've learned a few things. How that'll play out in real life, I have no idea.
The author is not trying to tell you what dogs think, but to give the reader more of an idea about how they experience the world, what is important, and what isn't. And along the way, she thoroughly debunks the whole "dogs are *this* close to being wolves" quite effectively.
I still don't want a dog, but I found this an interesting read.
