There are a few home remedies that can help stop diarrhea in dogs. The first is to feed your dog a bland diet of boiled chicken and white rice for a few days. This will give their digestive system time to rest and recover from whatever caused diarrhea in the first place. Additionally, adding plain yogurt to their food can help restore the healthy bacteria balance in their gut, which can also help reduce diarrhea symptoms. Another remedy is to give your dog activated charcoal tablets or powder mixed into their food. Activated charcoal helps absorb toxins and other substances that could be causing diarrhea, so it can effectively reduce symptoms quickly. Finally, you should ensure your dog is hydrated by providing plenty of fresh water throughout the day. Dehydration can worsen diarrhea, so keeping your pup well-hydrated during this time is essential.
