Leptospirosis In Dogs

Although leptospirosis is a disease most often seen in dogs, it can be easily transmitted to their caring owners. Today, our Enterprise vets discuss the causes and symptoms of leptospirosis in dogs and explain why it's important to have your dog vaccinated.

Leptospirosis In Dogs

Leptospirosis is a disease that can endanger the health of your dog, farm animals, and family. It develops when a bacterium known as Leptospira (seen in soil and water all across the world) makes a substance contaminated by infected urine. Leptospirosis has also been found in cats that have fed on host animals like rodents.

Almost everywhere in the world has been reported to have this bacteria, but it's more common in warmer climates that get high amounts of rainfall. According to research, this disease has slowly spread into areas of the United States.

Because leptospirosis is a zoonotic disease, it can be transmitted from animals to humans. People can contract leptospirosis from contaminated water sources, wild animals, livestock, and other pets, just like dogs. The majority of leptospirosis outbreaks in humans are caused by contact with contaminated water.

Causes Of Leptospirosis In Dogs

Almost any pet could be at risk of getting leptospirosis, regardless of where in the world they live (urban, suburban, or rural areas). Below we have listed factors that could put your dog at a higher risk:

  • Exposure to or drinking water from streams, lakes, rivers, or puddles
  • Contact with rodents like squirrels or rats, or other dogs (such as in dog parks, boarding facilities, or urban areas)
  • Exposure to wild animals or farm animal species that may pass infected urine, even in your backyard

Signs & Symptoms Of Leptospirosis In Dogs

Leptospirosis symptoms in dogs include:

  • Increased drinking and/or urination
  • Diarrhea
  • Decreased appetite or not eating
  • Shivering or fever
  • Jaundice
  • Vomiting
  • Weakness
  • Muscle pain, stiffness, or reluctance to move
  • Depression
  • Conjunctivitis (red eye)
  • Dyspnea (difficulty breathing or coughing)
  • Inability to have puppies

Diagnosing Leptospirosis

Microscopic Agglutination Test: This is the gold standard for diagnosing leptospirosis, and it detects the presence of antibodies against Leptospira in the dog's blood. Infection is confirmed if the level of antibodies (called a 'titer') is high enough.

Treatment & Prevention Of Leptospirosis In Dogs

As with most diseases, it's more beneficial to prevent leptospirosis than treat it. If your dog hasn't been vaccinated against this disease, ask your veterinarian if they recommend it for your dog's lifestyle.

If found early enough, your dog's chance of surviving leptospirosis is approximately 80%, but their kidney and liver function can be severely impaired. This is one of the reasons why it's important to prevent this disease with vaccinations.

At West Gate Veterinary Hospital our veterinarians offer the leptospirosis vaccine for dogs that are between 10 –12 weeks old as part of our dog vaccination schedule. Once your pooch has received their initial leptospirosis vaccination, your puppy will need a booster shot three to four weeks later. After this, your dog will need annual vaccines to keep them protected during their lifetime.

Because humans are able to get leptospirosis from their dog, it's best to avoid coming into contact with your dog's urine with bare hands if you think your dog may be infected. Always wash your hands after interacting with your dog. We highly recommend wearing rubber gloves while you are cleaning locations where your pup may have soiled, and be sure to disinfect any spots where your dog has urinated. One of the best ways to disinfect your home is to use a household disinfectant or diluted bleach solution (make sure to keep these potentially harmful substances away from your pets!)

Prescription antibiotics can be used to treat dogs with leptospirosis and can also keep other members (pets and humans alike) in your home from getting infected.
