I echo Archie Beans post exactly!
When you've been on the steep learning curve of the challenging puppy, you understand how sensitive they are. I too found taking him anywhere as an adult, quite tense. M-in-law was a nightmare, she seemed to be magnetically attracted to fussing around near him, offering countless cups of tea , and tins of biscuits being waved around . I could have bitten her myself when she dropped a little side table on him! My mantra to every one was.. Don't stare at him, just ignore him and he'll be fine. And he was, bless him. As for guarding? Well I conquered that by not being the slightest bit interested in the object of desire.
Such a complicated little soul. The more work you put into a dog, the more you get out of them, and the more you love them. Now I'm all weepy.
