Distemper (dog fever) is a highly contagious disease caused by the canine distemper virus, which is highly contagious and has a mortality rate of over 80%. The symptoms of distemper are initially a temperature of 39.5 to 41 degrees Celsius, loss of appetite, depression, watery discharge from the eyes and nose, sneezing and diarrhoea. In the next 2 to 14 days, the temperature rises again, coughing, purulent nasal discharge and purulent eye droppings are already in the middle stage of distemper. There is also secondary gastrointestinal illness, vomiting, diarrhoea, loss of appetite, high depression and lethargy. In the later stages of distemper, the typical neurological symptoms of foaming at the mouth and convulsions appear, which are usually difficult to cure, although there are some successful cases.
