Dogs are the most loyal animals and the best friend of human beings. Therefore, many dogs are generally very spiritual and have deep feelings for their owners. They are worried that their death will bring sadness to their owners, so they will run away and die without a place to die.
Dogs are similar to humans. Dogs have only a decade of life. They are anorexia before death, have no energy, and like to be alone. The most obvious thing is that you crawl in the nest or on the ground without moving, and you always hum, you have a premonition before you die and you will dig a hole, but you usually won't die at your own home.
When touching the dog's body surface, it may feel pain or get angry at the owner's touch. Frequently shake your head or use your front and rear limbs to scratch the fixed parts of your body. Walk abnormally, unstable gait or lame. Intermittent convulsions and spasms, accompanied by foamy vomiting, lying down and other symptoms. Drink water frequently and scream. Vomiting more than twice within 12 hours.
