Yes, dogs can still contract leptospirosis even if they are vaccinated. While the vaccine significantly reduces the risk and severity of the disease, it only protects against specific strains (serovars) of the bacteria, not all existing variations. Vaccinated dogs might still get sick if exposed to a non-covered strain.

How common is leptospirosis in vaccinated dogs?

Leptospirosis is uncommon in areas where dogs are routinely vaccinated. However, disease outbreaks are still seen occasionally because vaccines protect against only the four most prevalent strains of Leptospira. Leptospirosis was once more common in rural, wooded areas, but it is now commonly found in urban settings.

What are the early signs of leptospirosis in dogs?

Early signs of leptospirosis in dogs are often vague, mimicking other illnesses, but commonly include fever, lethargy, loss of appetite, vomiting, diarrhea, increased thirst/urination, and muscle pain/stiffness, with jaundice (yellowing) and difficulty breathing appearing as the disease progresses, requiring urgent vet care due to potential kidney/liver failure.

How long can my dog get leptospirosis if vaccinated?

However, because there are many strains (types) of the bacteria the vaccine may not give 100% protection, and protection may last for less than one year. If your dog gets leptospirosis, it can still get sick again with a different strain of leptospirosis.

Does vaccination prevent leptospirosis in dogs?

Can dogs get Lepto from eating grass?

Yes, dogs can get Leptospirosis (Lepto) from eating or licking grass, dirt, or puddles contaminated with the urine of infected wild animals like rats, raccoons, or deer, as the bacteria live in moist environments and spread through urine. Contact with contaminated water, soil, or even licking contaminated paws after walking outside are common infection routes, making vaccination a key prevention strategy against this serious, potentially fatal bacterial disease.
 

Do dogs really need the Lepto vaccine every year?

Given that every dog is at risk, an expert panel has recommended that all dogs are vaccinated for leptospirosis annually rather than every three years.

How do I get rid of leptospirosis in my yard?

Can a dog survive leptospirosis without treatment?

What is the 3 2 1 rule for vaccines?

The "3-2-1" rule is a guideline for monitoring lumps at feline vaccination sites, indicating a lump needs veterinary investigation if it's still present 3 months after vaccination, is larger than 2 cm, or is growing larger 1 month after appearing. This rule helps identify potentially dangerous injection-site sarcomas, rare tumors that can develop in cats, prompting biopsies for suspicious masses. 

Do dogs shed Lepto after a vaccine?

However, for those who recover, they may become asymptomatic renal carriers for extended periods and shed infectious leptospires into the environment. This is a large source of infection, as rats can be carriers but do not show signs of infection. Whilst treated dogs can shed leptospires, so can vaccinated dogs.

How long can dogs get Lepto even if vaccinated?

We are not sure how long immunity lasts after vaccination but it is likely to be less than 18 months in the case of Leptospira. For this reason, we advise yearly boosters.
