I love these dogs.
I went to Malta for my honeymoon and the appartments where we stayed had one of these little fluff balls. It used to follow my hubby and me into our room and stay there for hours. The owners knew where it was (they found this out after the first day of us being there and they watched it follow us. They came and knocked on our appartment door to apologise about their dog following us and (making a nuisance of itself - NOT), my hubby answered the door and they found their little dog sat on my knee hard fast asleep. I told them I would return it once it woke up.
It used to watch for us coming back in an afternoon for our relax before going out in the evening. For 2 weeks we had a dog for company every afternoon, we didn't mind and the owners got chance to go and do some shopping whilst we dog sat!!!!
