I have a 4 lb Papillon and she sleeps on all the furniture in the house, seat, arms, tops of back, etc. Her hair is not very thick but she sheds as much as my 19 lb long haired Maine coon cat. I can vacuum floors and furniture one day (having to empty it twice during process as it is bagless) and next day you can't tell I did it. Drives me crazy but couldn't do without my loves!!! But heck, I live by myself so if folks don't like the hair, they don't have to come visit....lol.
