Methods for preventing and treating canine distemper:

1. Regular vaccination. Puppies are immunized for the first time at 6 weeks of age; the second immunization is at 8 weeks of age; the third immunization is at 10 weeks of age, and should still be immunized once a year in the future.

2. Internal non-proliferation. Once a sick dog with signs of canine distemper is found, the sick dog should be isolated immediately, and contact between the sick dog and healthy dogs is strictly prohibited.

3. External defense input. During the epidemic period of this disease, it is strictly forbidden to bring in outside dogs, and try not to let the dogs come into contact with other dogs.

4. Disinfection. The kennels and items used by the sick dogs should be burned as much as possible, and the surrounding environment should be thoroughly disinfected with caustic soda, sodium hypoxonate, and poison.

5. Emergency prevention. For dogs that have not yet developed symptoms but may be infected and dogs that are threatened by the epidemic, emergency preventive injections should be carried out immediately with canine distemper hyperimmune serum.
