For those who remember my trouble with my new terrified poodle Rosalind

Again I want to thank those of you who tried to give me some help. Here is a short update:
She is doing much better. She seems to read my mood better than the Boxer, and thus still runs into the backyard when I am annoyed about something. I live in the city of Denver in an area with a very large population of squirrels (my fruit trees contribute to that, no doubt). Both dogs love to chase them. When the critters sit in the trees however Rosalind barks and barks at them. Since I like my neighbors I try to shush the poodle. By now she just turns around and barks back at me. No fear there at this point. I still cannot touch her when she eats, although she is now totally in my way when I get their food ready. If I am too slow for her she barks. She still gets car sick, but now I have a plan for that.
After reading several books about dog behavior and training, which all deal with either normal or fearful dogs, I found the right one over the web and got it from my library:" Help for your shy dog". This one fits for my Rosalind. So I will start over now following the author's suggestions. Drive her around one block at a time for instance. Obviously I made a lot of mistakes; but she is much calmer already.
Question to you people: Why does she want my arm in her mouth sometimes? She does not bite it, does not even put pressure on, but she does this mostly when I come home from shopping for instance.
Thanks again!
