*These are the manufacturer's recommendations for the age at when to start vaccinating and the booster schedule. Your veterinarian may have different recommendations for minimum age, boosters, and annual vaccinations based on the breed, health status, and potential of the dog to be exposed to the disease. Many veterinarians do not recommend the use of a leptospirosis vaccine (7-way or 8-way) in dogs less than 12 weeks of age. See Vaccination Schedule for Dogs.
