Please consider keeping Pearl on the bland diet for at least a couple more days. It won't hurt her, and gives her time to heal from whatever caused her vomiting. How is she doing?
When my chis are sick, we feed bland cooked chicken with white rice and add warm water (to make a "broth") for at least a couple of days or more, until they're well. When they're well, we go back to feeding them their regular dog food (Wellness Core) mixed in warm water and a little bit of cooked vegetables (peas, carrots, grean beans).
Bella is chocolate blue tri-color. RIP my precious Lina - we miss you so very much.
