Do you have a spoiled dog?

We've owned our dog for two years, we've had her since she was eight weeks old. About two months ago, while we were waiting to close on our home, we were staying at my parents house. They have a dog as well. When they feed their dog, they always add gravy, leftovers, or some type of people food to her dog food. While we were there, they did the same for my dog. We stayed with my parents for about six weeks. Ever since we've been in our home, our dog will not touch her dog food unless something is added to it. It doesn't have to be much, it can even be a little bit of canned dog food, but if it is just her plain dog food in the bowl, she won't touch it. I thought at first that she would eat it plain if she was hungry enough, but after she went two and a half days without eating, I couldn't stand it. She's spoiled now! I guess I should've never let her add things to her food while we were there. Do you have a spoiled dog? Do you add things to spice up your dog's food?
