I would rate Tucker (6months old) a 7 or 8. He has had a few health problems and he is a pistol. lol.. He has been pretty tough to train and he never stops going
He runs all day long untill he falls over from exhaustion. BUT I wouldnt trade him for the world, he is the best little cuddle buddy and he definitly adds some "life" to my house.
As far as expenses go.. a 10. Between the amount of money I have spent on food, (changing numerous brands) grooming fees (every 6 weeks) and medical it has been pretty expensive but well worth it.
