Adult dogs generally fast for half a day, while young dogs fast for about three hours. Generally, dogs only fast when they have diarrhea and vomiting. If the dog only has diarrhea, then the parents only Just need to fast. If the dog's vomiting and diarrhea are severe and frequent, parents should take the dog to the hospital for infusion in time to replenish the lost fluid.

Tips:

Fasting and water deprivation are generally used to allow dogs to heal on their own. Parents should not allow some very small puppies to undergo fasting after vomiting and diarrhea. After depriving water, the dog will heal on its own. The dog should be sent to the hospital promptly to replenish fluids and energy, find out the cause of the disease, and treat it symptomatically.
