Is 39°C Fever in Dogs? Understanding Canine Temperature

One: What Should a Dog's Normal Body Temperature Be?

Newborn puppies, within their first week of life, typically have a lower body temperature, ranging from about 34.5 to 36 degrees Celsius. As these young dogs grow and their vital signs stabilize, their body temperature will rise during the second to sixth weeks of life, averaging between 36 to 39 degrees Celsius. As the puppy's organs continue to mature, their temperature will settle around 38 to 39 degrees Celsius. For an adult dog, the normal body temperature is generally between 37.5 to 38.5 degrees Celsius. These temperature ranges are based on rectal measurements. The surface temperature is usually about 0.5 degrees Celsius higher than the rectal temperature to be considered accurate.

Two: Is a Dog with a Temperature of 39 Degrees Celsius Feverish?

In the case of newborn puppies, a temperature of 39 degrees Celsius is extremely high and requires immediate medical attention. For adult dogs, a temperature of 39 degrees Celsius falls within the range of fever. However, it may not always be indicative of illness, as it could be influenced by environmental factors such as temperature changes throughout the day and night. Therefore, when a dog's temperature reaches 39 degrees Celsius, it's crucial to closely monitor for any further increase. A fever is typically diagnosed when the dog's temperature exceeds 39.5 degrees Celsius.

Three: How to Properly Measure a Dog's Temperature

It is generally recommended to use rectal temperature measurement. This involves using a thermometer, applying a small amount of lubricant to the tip, gently controlling the dog, and then inserting the thermometer about 2 centimeters into the dog's rectum. The thermometer should be slightly angled and the tip should make contact with the rectal wall. Leave it in place for 4 to 5 minutes before removing to read the temperature. After use, the thermometer should be disinfected with alcohol to ensure hygienic reuse.
