If the vaccine is unopened, it can be stored in the refrigerator until it expires. However, if the vaccine has been opened, it can only be stored for about one to two days. First of all, it is recommended that the vaccine be used immediately after opening to avoid affecting the immune effect of the vaccine. Secondly, the vaccine can only be injected when the dog is healthy, otherwise it will worsen the dog's condition. Finally, when refrigerating vaccines, the temperature of the refrigerator needs to be between 2-8°C.

1. The dog needs to stay in the new home for more than 15 days, fully adapt to the environment at home, and survive the stress period, vaccination can be considered.

2. Internal and external deworming can be done in advance one week before vaccination, so as to eliminate parasites, make the body healthier, and the effect of vaccination will be better.

3. After the vaccination, pay attention to keeping warm. Keep the food, drink and environment the same as before within a week. Reduce going out and exercise. You should not take a bath within a week and have as little contact with dogs outside as possible.
