Leptospirosis is an increasingly common, serious bacterial disease in US dogs, with studies indicating a 5.4% test-positive rate nationwide and significantly higher prevalence in warm, wet, or urban areas. While 100-200 cases may be identified annually in some reports, the disease is considered underdiagnosed. Risk is highest for young, male, or small-breed dogs.

Can dogs get lepto from 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.
 

What is the most common reservoir for leptospirosis within the United States?

Rodents are an important reservoir for Leptospira, but most mammals, including dogs, horses, cattle, and swine, and many wildlife and marine animals, can be infected and shed the bacteria in their urine.

How fatal is Lepto in dogs?

Leptospirosis is responsive to antibiotics and complete recovery is possible, but some dogs that survive may be left with chronic kidney or liver disease. Some dogs may not survive if the infection has caused significant organ damage or severely affected the ability of blood to form clots.

Can a vaccinated dog get leptospirosis?

Vaccination. In the United States, you can get dogs, cows, sheep, goats, pigs, and horses vaccinated against leptospirosis. The vaccine doesn't provide 100% protection because there are many strains of the bacteria that cause leptospirosis, and the vaccine doesn't provide immunity against all strains.

Do dogs get lepto 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.

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.

What is the most common way to catch leptospirosis?

Leptospirosis is caused by an infection with the spirochete bacterium Leptospira and is most often spread through exposure to the urine of infected animals either from direct contact or from contact with soil or water contaminated by the urine.

What are the side effects of the leptospirosis vaccine for dogs?

Side effects of the leptospirosis vaccine can include mild reactions at the injection site, such as soreness or swelling. In rare cases, dogs may experience allergic reactions or more severe responses. However, adverse effects are generally uncommon and outweighed by the benefits of vaccination.

What kills leptospirosis bacteria?

Leptospirosis bacteria are killed by strong disinfectants like diluted bleach, quaternary ammonium compounds, and hydrogen peroxide, and also by soap, drying, and acidic solutions (vinegar, lemon juice), while antibiotics such as doxycycline, penicillin, and ceftriaxone are used to treat infected humans and animals, with severity dictating IV vs. oral administration.
