Dogs with diarrhea and blood but normal spirits may be caused by a variety of reasons, including food intolerance, indigestion, parasitic infection, or intestinal scratches caused by accidental ingestion of foreign objects. In order to solve this problem, you can try the following measures: Suspend feeding: First of all, it is recommended to suspend feeding for 12 to 24 hours to give the stomach time to rest. Provide adequate hydration: Make sure your dog has enough fluids to prevent dehydration.

Medical treatment: If the dog's symptoms are caused by a bacterial infection, the veterinarian may prescribe antibiotics. At the same time, probiotics can help restore intestinal health.

Diet management: After resuming feeding, start giving easily digestible food, such as cooked chicken breast and white rice. Then gradually increase the proportion of your regular diet until complete recovery.
