As I've noticed with all my pets and myself
I think that would be due to diet.
Put her on a good food.
We use Nutro Max (no by products). Around $7.00 a month, a cup a day (follow instructions), but well worth it for a lifelong companion.
Not endorsing but just a example for a healthy dog.
I can see feeding natural but I think it would take more than chicken to do it.
