Distemper disease in dog or CDV, has three distinct phases based on its symptoms:

  • 1st phase: The virus attacks the respiratory tract, causing excessive nasal discharge, which gives the disease its name “distemper.” There is also a significant amount of mucus in the eyes.
  • 2nd phase: The virus affects the digestive system, leading to severe vomiting and diarrhea, which are particularly dangerous due to the risk of dehydration.
  • 3rd phase: The distemper virus attacks the nervous system, resulting in seizures, muscle spasms, and paralysis.
