If the smell is really bad, it could be yeast infection. You should not bath the dog more than once a month. That would strip the oil off the coat and skin. The dog would start to have rash. May try to go to pet shop and see any solution.

I would open the window when you can to air the house/apartment.

I think you cannot bath the dog more often than once a month. Otherwise you would strip too much oil from the dog and it would start to be itchy. You can brush the dog as often as you like, that can reduce shedding in the house.
