Dog picky on food

My dog use to be a picky eater, but we've found a food that she seems to like with the purina one and the costco variety. She's a larger dog so it has to be weight control or adult giant breed foods. All foods that I've looked at for her have been checked by our Vet as well.

She's been on her healthy weight food for about 9 months and its been really good on her. Her coat looks awesome and she's had very little gassyness which can be a problem for giant breeds.
