In the mean time I would really cut back on the pellets she gets and go more fruits and veggies. Do you give sprouts? Mine love sprouted beans, quinoa, brown rice, lots of greens like collard, kale, mustard greens, dandelion greens, Italian parsley, cilantro. Quinoa and cilantro are really great liver cleansing foods as well as beets and carrots, arugula, dandelion greens, apples, and broccoli.
Really take a look at some of the food recommendations on the land of vos website.
