When people are vaccinated in childhood, they also have a certain chance of getting seriously ill. Since you have a dog, don't save money, go to a regular place for vaccination. One is to ensure the health of the dog in the future, which is also good for the owner.
Not expensive either. It should be one or two hundred yuan. After vaccination, you will be given an epidemic prevention certificate and vaccinated regularly every year. The doctor will tell you the precautions.
I wish your dog health and happiness ~ ~ ~
