What type of dog food do you use?

I also feed my dog Purina one, sometimes though, we will switch the brands now and then just to give her more variety. She honestly seems to prefer regular ham over dog meat though. Would it be classed as spoiling the dog to feed her regular human food? (always meat). It's just sometimes, she refuses to eat any dog meat but it's a little strange because this is only on occasions, and for the most part she is fine with it.
