So, here's an update on Lucy the terrier. Background reminder: I live alone with Lucy. She bit me several times in her first weeks, but became very attached. Using your methods, we are now able to walk quietly on the street, and to welcome family members and friends into our home. I have successfully resumed dogsitting, and Lucy is willing to share me with other dogs. Currently, I am turning every sound from the street into a cuddle fest; a slammed car door, the UPS and mail trucks, the house builders working behind us, are all cues for extravagant affection. I think I'm going to recruit dog savvy people to come to the door as a next step. Thanks so much!
