If the health is less than 1 year for about 3 months, it belongs to the susceptible period, and the physical condition is not very good, so there is a great possibility of being infected.
If you are older than 1 year and have passed the susceptible period, under normal circumstances, even if you are infected, you will not have typical symptoms.
As a preventive measure, you can add some antiviral oral liquid to healthy dogs to help enhance their resistance.
Because there is no 100% answer to this question, I can only help you so much. I hope healthy dogs will not be infected ~
Precautions: If you haven't come into contact with healthy dogs, you should disinfect your shoes and clothes. You must choose a disinfectant that can disinfect the virus or bask in the sun and underground. This is the simplest and most effective disinfection method.
If exposed, give healthy dogs a certain amount of antiviral oral liquid such as Gankang, but reduce the dose. After all, you should take it as a preventive measure.
I hope the above answers are helpful to you.
