Generally speaking, dogs will enter the recovery period within two to three days. In the recovery period, dogs can only eat syrup gruel to reduce the burden on the stomach. You can add some high-energy probiotics to porridge to speed up the recovery of gastrointestinal flora. After three or four days, the dog will recover. The whole illness will last about two weeks from the beginning to the end. If the symptoms are not relieved after taking the medicine, you should go to the pet hospital in time.
