Have you ever deworming your dog? If not, I suggest you do it for your dog. When there are parasites in your dog, it will cause emaciation, loss of appetite, poor spirit, rough hair and so on. Generally, it is enough to use insect repellent tablets in the body to deworm dogs. Adult dogs generally need to be deworming every three months. After deworming, it can also regulate the dog's stomach. If the stomach is not well absorbed and digested, it will also cause emaciation. I hope it helps you.
