Poor Dolce - she sounds a bit frigtened and stressed..... When Bramble first came home (although she was only 8 weeks) it was very, very difficult for her.... all the new sounds, smells, things and people..... I made sure that when the children were not around, I would sit on the floor - come down to her level - as leaning over her head straight on is a threataning gesture to dogs - talking quietly. This is where a cage comes into its own - its her haven, so keep the kiddies away from the crate - don't try and pull her out of it, and be calm, quietly spoken, and (I know this one is difficult, having a house full of boys myself) try and keep the kiddies relatively calm and quiet for a few days until she has settled in, as sudden loud noises and charging around will scare the living daylights out of her, AND very importantly, as she is 5 months, get her socialised - go to puppy classes and walk her places where there are people around.
Hope this helps..... and Gwen aileys book is brilliant.....
