Why do dogs howl before they die

Dogs howl before they die because they are in pain, not only physical pain, but also psychological pain. Dogs have feelings for their owners, and they can also sense that their end is approaching and want to say goodbye to their owners. Maybe the dog wants to tell its owner that you will be a dog in the next life, or maybe it means something else. In short, the death of a dog is heartbreaking for every owner, so it is very important to pay attention to the health of the dog while he is alive.
