The dog's body temperature is usually between 38°C and 39°C, which can be measured through the following steps:

First prepare an electronic thermometer or glass thermometer, and prepare some lubricant such as Vaseline or lubricating oil. If you are using a glass thermometer, you need to disinfect it with alcohol first, and shake the thermometer to bring the mercury ball in the thermometer to the lowest point. Apply lubricant to the end of the thermometer for insertion into your dog's anus. Put the dog in a relaxed position, either sitting or lying down, with one person controlling the dog and another person taking the temperature. Slowly insert the thermometer into your dog's anus and hold it there for about 1 minute until the thermometer rings or the numbers display your dog's temperature. Pull out the thermometer, wipe it clean with a disinfectant wipe, and store it in a dry, safe place.

It should be noted that when measuring the dog's temperature, be sure to avoid inserting the thermometer forcefully to avoid damaging the dog's anus. If you are unsure about how to properly measure your dog's temperature or have any questions, it is recommended to consult your veterinarian.
