Dogs with food accumulation will experience symptoms such as anorexia, poor energy, vomiting and diarrhea, bulging abdomen, constipation, etc. This is generally caused by irregular diet, food deterioration, unhygienic tableware and other reasons. You can feed your dog some probiotics or digestive tablets to help digestion, and then feed your dog regularly and quantitatively every day. It is best to clean the tableware before meals, and do not feed your dog spoiled or expired food.
