This depends on the choice of the parents. Compared with the six-linked vaccine, the eight-linked vaccine prevents one more leptospira. If parents are more concerned about this disease, they can inject the eight-linked vaccine. If they are not so concerned, they can choose other vaccines. The diseases prevented by the vaccine increase from the second dose to the eighth dose. Parents can choose the vaccine according to their own needs.
Tip:
To inject a dog with a vaccine, you need to meet the age limit. When injecting the vaccine, you must ensure that the dog is completely healthy. You need to observe it for half an hour after the vaccine is injected.
