The interval between vaccinations for puppies is 21 days. First, the puppy is vaccinated for the first time at 48 days of age, and three doses of infectious disease vaccines are required. The dog can be tested for antibodies and injected with rabies vaccine 15 days after the three injections of vaccine. The vaccine is the level of antibodies shown in the dog's body. The dog's body's immunity will gradually decline over time, so a booster vaccine is required every year. It is necessary to ensure that the dog is in good health before being vaccinated.

Notes on dog vaccination:

1. Generally, after a dog is vaccinated, the doctor will recommend that a dog can only be bathed one week later. The main reason is that the dog is afraid that if the wound is directly exposed to water after vaccination, it will cause infection.

2. Before vaccinating your dog, you must first ensure your dog’s physical health. The vaccine is a kind of virus, and only if the dog's body is healthy can it get a normal immunity. Therefore, before getting the vaccine, you should take the dog for a full-body health check-up.

3. Choose a regular hospital. Everything is guaranteed. Regular hospitals are safe for medication and have good technology. Therefore, don’t choose a cheap hospital just to save money. Otherwise, your dog’s life may be in danger. .
