The Bordetella vaccine, which protects dogs against kennel cough, is typically administered as follows: Puppies:

• Initial Bordetella vaccination is given between 6 to 8 weeks of age.
• A booster dose follows about 3 to 4 weeks later, usually around 10 to 12 weeks of age.
• Some protocols may include a second booster around 14 to 16 weeks, depending on veterinarian advice

Adult Dogs:

• Booster vaccinations are recommended every 6 to 12 months depending on the dog's risk of exposure.
• Dogs frequently in contact with other dogs (e.g., at boarding facilities, doggy daycare, training classes, dog parks) should receive the vaccine every 6 months to maintain strong immunity.
• Dogs with low exposure risk (primarily staying at home) may only need the booster annually

Vaccine Forms:

• The vaccine can be given as an injection under the skin or as an intranasal spray.
• The intranasal form can be given as early as 6 weeks, while the injectable is usually for dogs 8 weeks and older

Summary:

• Puppies: 2 doses starting at 6-8 weeks, booster(s) as recommended.
• Adult dogs: Booster every 6 months if high exposure risk; otherwise, annually.
• Consult your veterinarian for a schedule tailored to your dog's lifestyle and local requirements.

This schedule helps prevent kennel cough, a contagious respiratory infection caused by Bordetella bronchiseptica and other agents
