A dog suddenly walking around abnormally may be caused by reasons such as wanting to go out, wanting to defecate, having abdominal pain, wanting to vomit, or missing its owner. The dog needs to be observed to see if there are other abnormalities. If If you have no other symptoms, you can take your dog out for a walk to relieve your mood. If you have vomiting, diarrhea, poor energy, loss of appetite, anxiety, etc., it is best to take your dog to the pet hospital for examination to avoid delaying the condition.
