I think you should stay with real food. It's healthier. No dog food is safe!! You do not know what is in the dog food even if they have the ingredients labeled. That can be very deceiving and are not government regulated. Please read these sites about what goes into dog food and buy Ann N. Martin's book titled FOOD PETS DIE FOR.
