If the effect is poor, antibiotic treatment may be considered. Considering that the dog is only 20 days old, the use of compound lysozyme or penicillin antibiotics is generally preferred to reduce damage to the body.
If it is an adult dog, you can fast for the dog for one day, and then feed the dog some easily digestible food, such as bone soup, egg porridge, etc., and mix probiotics into the dog's dog food. Bacteria can regulate the imbalanced flora in the gastrointestinal tract and can be used as a conditioning drug to assist treatment.
