There are many symptoms of a dog before it is about to die. For example, the dog was sick and had no strength at all before death, but if the dog suddenly becomes lively and seems to have a lot of energy, this is a sign. There are signs of a comeback. The dog wants to make a last ditch effort to leave a happy side to its owner, but the dog will die soon after.

In addition, when a dog feels that it has little time, it will often stick to its owner, and its eyes will follow this. People move as they move, because they want to imprint the owner's appearance in their mind, and they are also reluctant to leave the owner and want to see more.
