If your dog doesn’t want to eat, you can give it some of its favorite snacks or canned food. If your dog still doesn’t eat, it may be that you are not feeling well, and it is best to take it to the hospital for examination. Many times, dogs will not eat or drink when they are sick, and they will have no energy. The owner needs to carefully observe the dog's condition. If any abnormality is found, treat it in time. You can usually feed the dog some probiotics to promote digestion.
