Its the same story here! Joe (my fiance) is also a big dog person and he plays very rough with Lucy. I always worry he is going to hurt her. It is strange though because she adores him and goes crazy when he comes over. At the moment I am trying to convince him we need a yorkie when we move in together as we both live at home and Lucy would stay when I move out as she is the family dog, but he is having none of it! Now do I live without yorkie or dump him??!!
