Banjo is the little dog I was referring to initially, and he was also an (emotionally) broken dog when he came to us from a home where he was kicked and abused. No wonder it took time for him to trust, but there were still volunteers who made the effort and with them Banjo was a different character altogether, sweet and affectionate. I can't even remember how long he's been waiting for his chance, although it's years rather than months, and finally today it came. Now we are holding our collective breaths to see how it turns out, hoping that all goes well and Banjo will stay for ever.
