  1. After the fast is over, start your dog back on a bland diet of white rice cooked with extra water and mixed with small amounts of baby food for protein and flavor; for each cup of dry rice, use two to three cups of water. Continue to add probiotics to her food, using at least 2 to 10 billion viable bacterial organisms in each meal you serve; to determine the level of “viable organisms” or “colony forming units” (CFUs) present in a probiotic such as acidophilus, look on the label—a reputable manufacturer will list that number.

  2. None of these options should be used because the result is similar in humans and result in constipation and creates an improper balance and cycle of constipation and diarrea.

    Administering soaked chia seeds and adding a little ginger powder is a better option for many reasons. Vomiting and diarrea can result in dehydration and loss of electrolytes. Chia seeds addresses this issue when soaked. Ground ginger is an excellent option for all digestive upset. Loose to violent bowel movements snd vomiting.
