Sick dogs love to eat white rice with chicken (without the peat), no seasoning of course. Recovering dogs also like unseasoned canned pumpkin (very rich in minerals and vitamins) and it will help your dog to recover quickly, just 3 or 4 tablespoons at a time. Shredded chicken, unseasoned and diced, you can also give it to your dog as a treat. Bone broth is great for an upset stomach and bone marrow is very nutritious too. Finally, meat-based baby foods that don't have onion or garlic are nutritious, easy to digest and will help your dog get his strength back quickly. Don't forget water, because a dog that drinks his water ration is a happy dog, especially in hot weather.
