A rat terrier's normal temperature is 101 to 102.5 degrees Fahrenheit (38.3 to 39.2 degrees Celsius). To take your dog's temperature, you'll need a rectal thermometer. Put some petroleum jelly on the bulb of the thermometer. Ask someone to hold your dog's head while you lift his tail and insert the thermometer about an inch or so into the rectum. Do not let go of the thermometer. Hold it in until the temperature is read (about 3 minutes for a mercury thermometer), and then remove gently.
