Heart rate, respiratory rate, temperature, and urination and defecation are all physiological signs that can tell you about your pug's health. Like people, dogs have ranges for normal temperature, heart and respiratory rates, and elimination. The following values can help you assess your pug's condition.
The normal temperature range for a dog is 100 to 102.5 degrees Fahrenheit, with the average at 101.3. If your pug has a fever, he could be suffering from heat exhaustion or heatstroke (common in this breed), infection, or pneumonia. Take your pug to the veterinarian any time his temperature goes above 103.
To take your pug's temperature, use a rectal thermometer. Lubricate it with petroleum jelly or K-Y Jelly. While someone else holds the dog, lift his tail and gently insert the thermometer one to three inches into the anal canal, using a twisting motion. Don't force it. Leave the thermometer in for the amount of time recommended by the manufacturer, or for two minutes. Don't let your pug sit down while you're taking his temperature or the thermometer may break. If this happens, take him to the veterinarian to have it removed.
Dogs lower their body temperature by panting. Panting allows water to evaporate from the mouth, tongue, and lungs, and exchanges warm air in the body for cooler air from the environment.
