The best treatment for dog diarrhea:

1. Adjust the diet structure. Feed your dog more foods high in protein and vitamins, fresh fruits and vegetables, and avoid foods heavy in oil and salt.

2. Keep warm. Place the kennel in a warm environment to prevent the dog from lying in a cold and damp place for a long time.

3. Antidiarrheal medicine. Dog diarrhea is mostly caused by gastrointestinal problems. Probiotics have a good regulating effect on the gastrointestinal tract and can promote digestion and absorption. If the diarrhea is severe, you can also feed the dog montmorillonite powder and white clay.

4. Fasting. When the dog's diarrhea is severe, the dog can be fasted for a day until the excretion improves, but attention should be paid to supplementing the dog with nutrient solution to prevent dehydration.

5. Deworming. Dogs infected with internal parasites can also cause diarrhea, so dogs must be dewormed regularly.

6. See a doctor. If your dog's diarrhea is severe, accompanied by nausea and vomiting, loss of appetite, lethargy and other symptoms, he should go to a pet hospital for treatment immediately.
