When your dog is ill, you may have to determine whether or not he has a fever by taking your dog's temperature. It's relatively easy and all you need is a thermometer. Learning how to take your dog’s temperature properly can help determine if immediate veterinary care is needed.
Your dog’s normal rectal temperature is 100.5 to 102.5 degrees Fahrenheit. Higher temperatures may necessitate a trip to your veterinarian, depending on other symptoms. Feeling the ears, nose or head is not considered a reliable method; you have to determine your dog’s internal temperature to find out for certain. This is done using an oral or rectal thermometer, either digital or mercury. Ear thermometers can also be used in dogs. They are generally fast and easy but it is essential to use a proper technique to obtain an accurate temperature reading.
Instructions for Rectal Temperatures
Some dogs will allow you to take their temperature, but others don’t like it at all. It might be easier if you get another person to assist by holding your dog. Then do the following:
If using a mercury thermometer, remember to shake it with a quick flick of the wrist until the mercury is below 94 degrees. Then lubricate the thermometer with petroleum jelly, KY jelly or other water-based lubricant.
Have your helper hold the head and front part of the body by tightly hugging your dog.
Lift the tail and insert the thermometer slowly and carefully into the rectum, located just below the base of the tail. Insert the thermometer about 1 inch and hold in place – two minutes for mercury thermometers or until the digital thermometer beeps.
Remove the thermometer and read the temperature.
Remember to lubricate the thermometer with petroleum jelly, KY jelly or other water-based lubricant. Insert the thermometer about one inch into the rectum and keep in place for 2 minutes.
