A dog suddenly not eating or feeling energetic may be caused by a variety of reasons, such as disease, environmental discomfort, food, indigestion, etc. The scavenger should check whether the food is fresh and replace or dispose of spoiled food in a timely manner.

If your dog is not eating due to indigestion or gastrointestinal problems, you can consider stopping the meal. After a period of time, probiotics or digestive tablets should be given appropriately. If your dog is also accompanied by vomiting and diarrhea, it may be because he accidentally ate something he shouldn't eat or spoiled food, etc., causing gastrointestinal disease and not wanting to eat.

For gastrointestinal diseases, the diet can be adjusted appropriately and the dog can be given drugs to aid digestion. Check your dog's mouth and teeth regularly to ensure they are growing healthily.
