If your dog's diarrhea is a little loose, it may be because the dog has caught a cold. You can prepare a dog mat for the dog when it lies down, or put clothes on the dog when it is cold. In terms of diet, you can give your dog some probiotics to regulate his stomach. Be careful not to let your dog eat too much, which will also cause diarrhea.

The digestive system of dogs is different from that of humans, so never give your dog leftovers from humans. High salt and fat content will cause great irritation to the dog’s gastrointestinal tract. Do not let your dog eat foods such as chocolate, onions, and grapes that can cause food poisoning in dogs.
