Lurk IS a good word. It just *feels* good in the mouth. I don't know why either. Thanks for the suggestions. I'll give them a try. And thanks for validating my pseudo-analysis of Owen's behaviours. I just hope it evens out. He was such a great sport at the park, until just recently. Glad it's probably hormones. While I can't think of anything that might have happened, I was a teensy bit worried something might have happened, at the park, or elsewhere when I wasn't looking. But, as I said, my rational side figured it was growing pains. Now the focus goes to getting him to a more comfortable place (more comfortable for me maybe!).
Thanks again. and in case anyone is interested here's his web page:
