Our first dog Jedi had taught us a lot about dogs. One lesson is the soft diet when the dog is suffering from diarrhea or has no appetite. Especially when a dog has no appetite, force-feeding is the only recourse. This soft diet has rice broth for the main ingredient with an egg yolk and a dash of salt. The mixture is injected using a syringe (with no needle, of course).
For the procedure: Boil one cup of rice in 4 cups of water. Let it boil for at least 5 minutes so the nutrients of the rice is extracted to the broth. When harvested from the stove, let it cool before adding the egg yolk with a dash of salt. Shake vigorously with a spoon or fork before serving. Depending on the size of the dog, 20 ml every hour is enough nutrients for a medium size dog like Jedi.
