What are the symptoms of distemper? The normal body temperature of a dog is usually 38.5 to 39.3°C, while a sick dog will have a fever of about 40 degrees and a biphasic fever. That is, the elevated temperature will suddenly disappear after a few days and then reappear. French bulldogs with distemper will also have increased discharge from the eyes and nose. At first, they will have a runny nose and eye droppings, and when the condition worsens, they will begin to discharge large amounts of purulent discharge, sometimes accompanied by symptoms such as redness and swelling of the eyes. In the early stages of distemper, the pooch will also show poor mental and appetite, becoming more and more depressed, less active, and very sleepy most of the time, and his appetite will be close to a state of desolation.
