Why do dogs leave home when they are about to die?

The reason why dogs leave home when they are about to die is because dogs can feel their own physical condition. Most dogs will leave their homes before death and choose to hide by themselves. Rise and wait for death. Because the dog doesn't want the owner to see it dying, and doesn't want the owner to be sad. The dog will hide in a place where no one is around and then die quietly. If your dog starts to avoid you and keeps hiding so that you can't find it, please interact with your dog more so that your dog can spend the rest of his time happier.
