Dog vaccines can prevent infectious diseases in dogs. The two combinations prevent canine distemper and parvovirus. Quadruple combination prevents canine distemper, parvovirus, infectious hepatitis and parainfluenza. The six-linked version adds Leptospira type 1 and 2 to the four-linked version. The Eighth Alliance has additional coronavirus and adenovirus type 2 on the basis of the Sixth Alliance. Dogs can usually be vaccinated when they are about 45 days old. Vaccination is the best way to prevent dogs from contracting infectious diseases.

Notes on dog vaccination:

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. before you can consider vaccination.

2. The dog has been kept at home for more than a week and has no obvious abnormalities (eating, drinking, and defecating at home are normal, no vomiting, diarrhea, and cough are seen, the dog is in good spirits, and the weight is up to standard). Only when the above conditions are met can the dog be vaccinated.

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.
