You can pay attention to the formula before buying.
Try to choose chicken, which is easier to digest.
If the dog can't digest corn, choose a formula that contains no corn or a small amount of corn.
As a reminder, the replacement of dog food should not be completed at once. Add about 1/5- 1/4 of new dog food to rice every day, and change it slowly after 3-5 days.
About other things
After diarrhea or vomiting, millet porridge is a good food to care for the stomach and has no irritation to the stomach.
Usually, you can feed your dog some apples properly, which is also good for your stomach (be careful not to be too cold).
Usually be careful not to feed milk, high salt, high sugar, high fat and spicy food.
Strengthen the nutrition and physique of dogs.
If the dog can't digest well, you can take a tablet for invigorating stomach and promoting digestion after meals, but the long-term improvement still depends on diet.
I wish the dog a healthy growth ~
