I have a new dog and 2 visiting dogs. The visiting dogs are here for a week, and my house now smells like dog stink. Old dog peed in 4 places downstairs, barfed on an area rug, and peed the whole way down the stairs. I got an estimate for carpet guys to do my whole house on monday and it's going to cost $250. Would I be better off just buying a machine? What do you have? What would you do?
