Yes, I bought the Turid Rugaas book (a woman!). I like to buy books when I can to support the author, and I do like this author quite a bit! (plus, I'm a book nut with a huge library.) But if you're tight on cash, I'd pass this one up until you can afford to expand your library. Someone recently posted this link regarding the book:

Stanley Coren's "How to Speak Dog" has more detailed dog language info, and is easy find used.
I also learned a lot when working Ixa's reactivity with a trainer and other dogs.
I've learned that if I'm soft (calming) with Ixa when she's hard, but rough or playful with her when she's loose, she has opportuinites to both feel secure, and enjoy amped up playtime, too. She has become a much more balanced and stable dog in the 3 months I've had her.
Here's the generalized picture of it with my girl:
Hard Ixa:If Ixa's ears are back and mouth is closed, if I can see the whites of her eyes, or she's yawning/lick lipping a bunch.
I'll use calm soft voice and slow movements. I don't pet her on the head or kiss her face. Instead, I turn my face, eyes and body to the side, not directly towards her face, and I pet her chest calmly. Sometimes I'll lay on the floor next to her and pet her belly, but with my head even with her chest, not her face. Sometimes I won't approach her at all, letting her come to me, or I'll approach her at a curve (from the side). I might do sniffing with her, where I sniff her and encourage her to sniff me. I usually do yawning, lick lipping, or blinking. It helps if I keep my face and eyes open in a big happy face. In this mood, I'll only train stuff she knows really well like sit, stay, shake, speak, and I'll treat a lot. When she starts doing downs, I know she's coming out of it.
Medium Ixa:If Ixa's ears are up and mouth is closed, and I see whites of eyes, or stiffness in her body, or she sighs:
I'll be silly, roughing up the fur of her chest or butt, but I'll turn my head away and still not move to fast. I might do some sniffing, yawning or blinking, too. I might sit on the floor with my back to her and hold still to let her investigate me. I might lay on my back and pat my belly for her to climb up and initiate play. In this mood I train to improve stuff we're already working on (longer crawl, longer stay, the reverse of a spin, etc), and I still treat a fair amount. If I push her too hard she'll blow me off.
Loose Ixa:If Ixa's ears are up and her mouth is smiling with tongue hanging out, eyes are soft or crinkled up, and tail is wagging:
I'll gather her face up to mine, I'll roughouse and play with her feet and tail, wrestling, playbiting her, and kneeling over her. We'll play chase and hide and seek, I'll paw her muzzle, and maybe even start a howling session. This is a great time for training new tricks, or capturing behaviors, or doing really active training like spining, jumping, reliable recall, directional running, and treat lots less (except in the recall). If I push the training too hard, she'll go back to medium mood.
Using calming signals, I can bring her up from hard to loose fairly easily if I need her up for a class or whatever. Anyway, she's rarely in that hard state anymore, unless there are specific stresses.
Weren't you writing about your BF and your dog recently? Is that affecting her moods?
