Leptospirosis is a bacterial disease caused by a group of bacteria called Leptospira that can affect dogs (and many other animals, including humans). It is typically more common in warm and wet climates (with high annual rainfall and flooding) but can occur anywhere.
What is Leptospirosis?
Leptospirosis is an infectious disease caused by the Leptospira bacteria. It can affect many animals, including dogs, livestock, and wildlife (although rarely in cats). The bacteria thrive in water and soil, particularly in warm and humid environments.
How Do Dogs Get Infected?
Dogs can contract leptospirosis in a variety of ways. Below are the three most common ways.
- Contact with Contaminated Water or Soil: Dogs can get infected through water or soil contaminated with urine from infected animals. This often happens in areas with slow-moving or stagnant water, such as puddles, ponds, streams, rivers, or lakes.
- Ingestion of Contaminated Food or Water: A dog can become infected if it drinks water or eats food contaminated with the bacteria.
- Direct Contact: The bacteria can enter through the mucous membranes (such as the eyes, nose, or mouth) or cuts or abrasions on the dog’s skin from rural environments and wildlife, especially rodents, or through dog-to-dog contact with an infected dog in dog parks, and boarding or training facilities.
Why is Leptospirosis a Concern?
Leptospirosis is a serious disease that can lead to severe illness or even death in dogs. The severity of the disease can range from mild, flu-like symptoms (that may resolve themselves in a healthy dog) to severe illness that can affect the kidneys, liver, lungs, and heart.
Below are three critical points you need to know as a dog guardian about this disease.
SYMPTOMS: Symptoms of leptospirosis in dogs can vary widely. They may include:
- Loss of appetite
- Fever
- Vomiting
- Lethargy
- Abdominal pain
- Diarrhea
- Jaundice (yellowing of the skin and eyes)
- Dehydration
- Drinking/urinating more than usual
- Weight loss
- Stiffness or muscle pain
Correctly diagnosing the leptospirosis infection can be difficult for the layperson because symptoms are often nonspecific to the disease until later progression.
So, if your dog shows any of the symptoms above, consult your regular veterinarian for further advice for a proper diagnosis and treatment plan.
ZOONOTIC DISEASE: Leptospirosis is “zoonotic,” meaning it can be transmitted from animals to humans through:
- Skin abrasions or cuts.Your eyes, nose, or mouth.
- Direct contact with urine or reproductive fluids from an infected dog.
- Contact with contaminated water or soil.
- Or eating or drinking contaminated food or water.
This makes leptospirosis a public health concern, especially for those who come into close contact with infected animals. Learn more about leptospirosis in humans on the Cleveland Clinic website.
PREVALENCE: The disease is more common in tropical or subtropical regions. However, it can occur anywhere, especially after heavy rains or flooding. Learn how to protect yourself and your animals after a heavy storm or flooding, which can spread the bacteria in urine from infected animals. (Source: CDC.gov)
Leptospirosis: Prevention and Treatment
Preventing leptospirosis in dogs involves a combination of good hygiene practices and vaccination. Here are four preventive measures:
- Vaccination: Vaccines are available for leptospirosis and can help protect dogs from the most common strains of the bacteria. It’s essential to consult with your veterinarian to determine the best vaccination schedule for your pet.
- Avoid Stagnant Water: Keep your dog away from stagnant water sources, especially in areas where leptospirosis is known to occur.
- Rodent Control: Rodents can be carriers of this bacteria, so actively control the rodent population around your home to reduce the risk of infection.
- Hygiene: Good hygiene practices, such as washing your hands after handling your dog and keeping their living area clean, can help reduce the risk of transmission.
The Final Word
Leptospirosis is a potentially severe disease that can affect dogs (other animals) and humans. Awareness and preventive measures are crucial in managing the risk of this disease. Regular veterinary check-ups, vaccinations, and good hygiene practices are vital to keeping your dog healthy and safe from leptospirosis.
Always consult a veterinarian for more detailed information, especially if your dog shows signs of illness.
