Normal temperature in dogs and cats: guidelines and when to worry
Normal temperature is higher than in people.
Many people are alarmed when they touch their pet and notice it is "hot". But the normal temperature in dogs and cats is higher than in humans. Without measuring it correctly, a fever or a drop in temperature cannot be confirmed. Knowing the guiding values helps to act with sound judgment.
Quick summary
- Normal temperature is higher than in people
- In dogs and cats it is usually between 38 and 39 ºC

Main steps
-
Step 1 — Know the normal range
In healthy adult dogs and cats, it is usually between: 38°C and 39°C It may vary slightly depending on the time of day.
-
Step 2 — When is it considered a fever?
A fever is generally considered to be above approximately: 39.5 ºC It should be assessed in conjunction with symptoms such as apathy or lack of appetite.
-
Step 3 — When is the temperature low?
Temperatures below approximately: 37.5 ºC They may indicate hypothermia and require attention. Special caution is needed for puppies and weakened animals.
-
Step 4 — How to measure it correctly
The most reliable way is with a suitable thermometer. The measurement should be done calmly and safely. If you don't know how to do it, consult your veterinary clinic.

Step 5 — Don't trust touch
Hot ears do not confirm a fever. A dry nose does not indicate a high temperature. Touch only provides guidance, it does not diagnose.

Temperature is just one more piece of information. You should also consider: energy level appetite hydration breathing

A temperature reading without other symptoms may not always be an emergency. However, an abnormal temperature accompanied by lethargy needs veterinary assessment. The overall clinical picture is what matters.
