Dogs can eat before vaccination, and eating will not affect vaccination. However, dogs need to have a physical examination before vaccination to ensure that they are in good health and are not sick, injured, pregnant or in poor physical condition. At the same time, the dog cannot go out before being vaccinated. After being vaccinated, the dog cannot take a bath or go out for the past ten days or so, otherwise it will be easy to get sick.

What should be paid attention to when vaccinating dogs:

1. Dogs with unhealthy constitutions, such as colds, allergies, severe calcium deficiency or parasitic infections, should be vaccinated. Immunize again after recovery to avoid suboptimal immunity.

2. Dogs that are too young (less than 6 weeks old) should not be vaccinated prematurely due to the presence of maternal antibodies in their bodies.

3. If you have just bought a puppy from a large market, it is best to raise it at home for 2 weeks and observe if there are no abnormalities before getting vaccinated. This can avoid interference with the immune plan due to physical decline due to stress response or the incubation period of the disease.
