The initial symptoms of distemper are mental atrophy, loss of appetite or loss of appetite, and plasma or mucus discharge from the eyes and nose, which gradually becomes purulent as the disease progresses, sometimes mixed with blood and with an unpleasant smell. The dog’s body temperature rises to 39.5-41C for about 2 days, then drops to normal temperature, the dog’s spirits tend to improve and appetite returns, but after 2-3 days the body temperature rises again and lasts for several weeks (biphasic fever), and the condition deteriorates again. There is dryness and even torpidity at the end of the nose, anorexia, often vomiting and pneumonia. In severe cases, diarrhoea occurs, with watery, foul-smelling faeces mixed with mucus and blood, and the dog is lethargic and dehydrated.
