Dog treasures are rare. It is said that a dog treasure that can sell for 280,000 yuan is a stomach stone of a canine, and it is a stone-like thing that grows in the dog's stomach. Most of the dog treasures are spherical or elliptical, with a general diameter of 1 5 cm. The surface is grayish white or grayish black, with a slight luster, and there are many round-like protrusions. The texture is firm and delicate, and scratches can be seen when nails are scratched. The cross section is white or ivory-white, showing concentric annular layering, and it is loose near the center, but it can't be separated. It smells slightly fishy and tastes slightly bitter, and it is powdery but has no sandy feeling when chewed. Goubao is a traditional Chinese herbal medicine in China, which has been praised as "three treasures" with Niuhuang and Ma Bao since ancient times. Goubao is a tight-selling commodity in the domestic and foreign pharmaceutical markets, and it is urgently needed by local pharmaceutical and foreign trade departments. 2. Identification of Dog Treasure According to data reports, 9%-1 10% of dogs have dog treasures, just because people can't or don't pay attention to identifying dogs with dog treasures and can't pick them up. Li Shizhen said in Compendium of Materia Medica: "A dog's treasure is born in a dog's belly, which looks like a white stone with a blue color. It is also a rare thing." Dog treasures are mostly produced in sick dogs, and these sick dogs often have the following characteristics: (1) Dog treasures are gradually formed, so the older dogs are more likely to have dog treasures, and the bigger the dog treasures they collect, the higher their value; (2) Physically weak, unwilling to walk, restless; (3) high body temperature, long-term fever, like a disease but not a disease; (4) The hair is messy, fluffy as grass, and dull, and even a large number of hair falls off and gradually becomes bald; (5) The eyes are dull and the conjunctiva is red and can't be cured for a long time; (6) eating less, eating irregularly and being picky; (7) Like drinking plenty of water, especially drinking salt water; (8) Daily fidgety, often giving out low moans and whines automatically at night. When a dog with the above characteristics is found, the stomach of the dog should be carefully examined when it is slaughtered. If a stone-like lump is found, it is a dog treasure.
