In recent years, leptospirosis has become a bigger concern for dog owners and veterinarians alike. With more information on how this disease spreads and its impact, experts are updating guidelines to keep our dogs safe. Here’s a clear look at what leptospirosis is, why it matters, and the latest guidance on vaccinating our dogs against it.
What is Leptospirosis?
Leptospirosis is a bacterial infection that’s spread primarily through the urine of infected animals, especially rodents, and can contaminate water or soil for weeks to months. Dogs can get infected when they come into contact with contaminated areas, which makes this disease a concern for both urban and rural pets. For dogs, leptospirosis can cause serious health problems, including kidney and liver damage, and can even be fatal if untreated.
Why is the Leptospirosis Vaccine Now Core?
Recently, the American Animal Hospital Association (AAHA) added the leptospirosis vaccine to its list of core vaccines. This decision was based on updated guidance from experts at the American College of Veterinary Internal Medicine (ACVIM). The ACVIM reviewed over a decade’s worth of new research on leptospirosis and found that the disease affects a wide range of dogs—regardless of breed, age, or location. They concluded that all dogs are at risk, whether they live mostly indoors, in urban settings, or in rural areas. Given these findings, the AAHA now recommends annual leptospirosis vaccinations for all dogs, rather than every three years as previously advised.
Key Reasons for Vaccination
- Protection Against a Serious Illness: Leptospirosis can affect multiple organs and lead to life-threatening complications. Vaccination significantly reduces the risk of infection.
- Prevalence Across Locations: Leptospirosis isn’t limited to specific climates or regions; it’s been found in urban and rural areas alike. Outbreaks have even been linked to dog boarding facilities, raising concerns for dog-to-dog transmission.
Vaccine Schedule and Possible Side Effects
Suggested Schedule:
- Initial Vaccination: Puppies can receive their first leptospirosis vaccine dose after 12 weeks of age
- Booster Dose: Four weeks after the initial dose.
- Annual Boosters: Recommended each year for continued protection.
Side Effects: As with all vaccines, some dogs may experience mild side effects like soreness at the injection site, mild fever, or lethargy. More severe reactions are rare but can include swelling or difficulty breathing. Small breeds may be more prone to side effects, so it’s important to discuss any concerns with your veterinarian.
New Developments in Leptospirosis Diagnosis and Treatment
The ACVIM’s updated guidance provides more insights for veterinarians on diagnosing and treating leptospirosis. Advances in testing, such as nucleic acid amplification tests (NAATs), help confirm leptospirosis cases more accurately. However, early treatment remains crucial, as delaying care can lead to serious complications.
If leptospirosis is suspected, the ACVIM recommends starting treatment with antibiotics promptly, especially for unvaccinated dogs showing symptoms of fever or kidney issues. Close monitoring and supportive care, including proper hydration, are key to recovery.
Risk Factors and Final Considerations
Because leptospirosis can impact a variety of dogs, from puppies to seniors, it’s important for each dog family to assess the vaccine’s potential benefits and risks. Lifestyle factors, such as whether a dog is exposed to outdoor areas frequented by wildlife or spends time in kennels, may influence the decision.
Ultimately, the choice to vaccinate for leptospirosis should be based on your dog’s unique lifestyle and risk factors, along with guidance from a trusted veterinarian.

By staying informed and working with your veterinarian, you can make the best choice to protect your dog’s health and well-being. At Happy Beard Schnauzers, we encourage each family to carefully weigh the risks and benefits of the leptospirosis vaccine based on their dog’s unique lifestyle. Since the side effects of this vaccine can be harsher than others, it’s important to consider your dog’s exposure risk. For example, a dog living mostly indoors in an apartment has less risk of encountering the bacteria than one spending lots of time outdoors hiking, camping, or around standing water. By assessing your dog’s routine and environment, you can make an informed choice with your veterinarian to keep your Schnauzer safe and healthy.
