A dog's diarrhea is caused by incorrect feeding

A sudden change in food, too much food at one time, or too much cold food will cause diarrhea. The owner should stop eating foods that are not easy to digest and give the dog some probiotics to promote digestion.

Dogs have diarrhea because they have caught a cold

Seasons change, and dogs are prone to diarrhea due to cold. First confirm that the dog has been vaccinated, and if the appetite is normal, take some measures to keep the dog warm, and then give the dog some anti-diarrheal medicine.

Dogs with diarrhea are suffering from infectious diseases

Dogs with severe diarrhea, accompanied by poor spirits, and elevated body temperature are suffering from infectious diseases. If the dog has been immunized, you can feed the dog 2w units of gentamicin together with probiotics and antidiarrheal drugs to observe whether the dog improves.
If the dog has not been vaccinated, be sure to take the dog to the hospital immediately. Because dogs do not have antibodies in their bodies, this will cause the dog’s condition to worsen rapidly.
