There are no conditions in a small place, and dogs will usually be dealt with by themselves after they die. Dogs must be buried deeply under a tree and away from the living environment to avoid contaminating the environment and preventing a series of hygienic problems that may occur when the body decays. Generally, in big cities, disinfection and epidemic prevention are required. Pet hospitals provide cremation services. The price is not expensive and the environment will not be polluted after incineration.
