A small infection will not infect the entire house. Parvovirus is mainly spread through feces and does not spread directly through the air throughout the house. But it can be spread through contact. For example, toys, bowls, cages and walls that dogs with parvovirus have used may contain viruses and must be thoroughly disinfected. After a dog is cured of parvovirus, there will be a three-month detoxification period. During these three months, try not to let it come into contact with other dogs.

How to prevent parvovirus:

1. For unvaccinated dogs, you need to avoid walking outside, and then clean and disinfect the environment, especially The dog's activity area, the pet owner's hands and the soles of shoes, etc.

2. Disinfect the dog regularly. Try not to bathe the dog or take the dog out to interact with other dogs before the young dog has been vaccinated. Take the dog out normally. Don't let him sniff other dogs' waste.

3. Dogs should be dewormed on time. It is recommended that external deworming be done separately from vaccination, and not at the same time.
