After a day of fasting, it is best for dogs to eat liquid food first, which is easier to digest. You can soak dog food in warm water or feed some porridge to the dog, and feed it in small amounts multiple times, and give the dog a little bit. Probiotics play a role in regulating the gastrointestinal tract. You should also pay more attention to your diet. Don't feed your dog random human food. Try to let your dog eat dog food as the main food and other foods as supplementary food.
