If Teddy has dental calculus, the two main methods can be used to remove it: brushing and scaling. Brushing is the easiest. There is a toothpaste specifically designed to remove dental calculus, but the effect is not as good as scaling, and it takes a longer time. , the owner needs to insist on brushing the dog's teeth every day. If the brushing is done properly, it will take about 3 months to see the teeth become obviously whiter. However, if you want to completely remove the dental calculus, it is best to choose teeth cleaning. Teeth cleaning is generally only done in a pet hospital. It can be carried out because anesthesia is required during the process, so it is also very risky. Only a regular and professional pet doctor can accurately control the amount of anesthetic, which can not only ensure that the dog does not wake up, but also reduce the harm of anesthetic to the dog's body. . Therefore, it is best to pay attention not to feed your dog teeth-sticking food, and brush your dog's teeth every day, which can greatly reduce the chance of developing dental calculus.
