German Shepherd puppies need 3 shots of combined vaccine to prevent infectious diseases and 1 shot of rabies vaccine. Usually, German Shepherd puppies can be injected with the first dose of combined vaccine when they are about 45 days old. The interval between each injection is about 21 to 28 days, and a total of 3 injections are required. Puppies need to be vaccinated against rabies after they are 3 months old. Afterwards, a booster injection of a combination vaccine and a rabies vaccine every year can effectively prevent dogs from getting sick.

Precautions when vaccinating German Shepherd dogs:

1. When vaccinating, the dog should be given a suitable temperature and be vaccinated in a healthy state.

2. You must go to a regular animal hospital to get vaccinated by a professional veterinarian, so as to ensure the effectiveness of the vaccine.

3. The dog should stay in the hospital for observation for 30 minutes after the injection. If the dog shows symptoms of edema, rash, or difficulty breathing, the doctor should be notified in time to receive an anti-allergic injection.
