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 to10 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.
Dosages for the two intestinal protectants mentioned above are approximate. Use the liquid medication, not the tablets, and give about 1cc of liquid for each 10 pounds of body weight up to three times daily. The bismuth subsalicylate has more anti-inflammatory activity, so may work better on patients with abdominal cramping.
If the diarrhea is very severe, you may want to also give your dog some loperamide (Imodium AD™), which can help to reduce fluid loss until the rice-water fast, white rice and acidophilus, and the dog’s own healing system can overcome the diarrhea. The published dose for loperamide in dogs is 2 mg (the standard-size capsule) for each 40 pounds of body weight, two to three times daily (this translates into 0.1 mg per pound).
