The older the Fadou is, the higher the heat resistance, and the fatter it is, the more heat-resistant it is. Generally speaking, if the temperature exceeds 30°C, the method will become very hot. This is mainly due to the fact that the skin of the fado has no heat dissipation function, and they can only dissipate heat through the respiratory tract and the soles of the feet. In addition, the mouth and nose of the doujin are relatively short and flat, which makes their respiratory tract very narrow. When the weather is particularly hot, their breathing rate is not enough to dissipate heat. Therefore, the owner should avoid taking the doudou out in summer to avoid the phenomenon of heat stroke. .

In addition, it is recommended that the owner keep the indoor temperature at about 22°C, and also need to trim the hair of the hood regularly, which can effectively help the hood to dissipate heat.
