Leptospirosis: How to Keep Your Dog Safe
At Peterborough Humane Society, we are committed to keeping the pets and people of our community safe. This year, there has been an increase in cases of leptospirosis in Peterborough and the surrounding area. This serious bacterial disease can affect both animals and humans, and we want pet owners to be aware of how to prevent it. The best protection for your dog is vaccination, and it is quick and affordable to access through our clinic.
What Is Leptospirosis?
Leptospirosis is a bacterial infection caused by Leptospira bacteria. It can affect many types of mammals, including dogs and people. In dogs, leptospirosis can lead to kidney and liver failure, and in severe cases it can be fatal. Some dogs recover fully, while others may face long-term health complications.
Symptoms in dogs can vary and may include vomiting, fever, lethargy, loss of appetite, bruising, bleeding, increased thirst or urination, and yellowing of the eyes or skin. Some dogs may develop inflammation in their eyes or show signs of general discomfort. While cats are rarely affected by leptospirosis, they can carry the bacteria without showing symptoms.
Leptospirosis is also a zoonotic disease, which means it can spread from animals to people. In humans, it often causes mild flu-like symptoms but can sometimes lead to more serious illness such as meningitis or liver problems.
How It Spreads
The bacteria that cause leptospirosis are found in the urine of infected animals. Wildlife such as raccoons, skunks, rats, mice, and possums are common carriers. The bacteria can enter the soil and water and remain active in moist conditions for weeks. Dogs can become infected when they sniff, lick, or drink from puddles or wet ground that has been contaminated. Infection can also occur through broken skin or mucous membranes.
Leptospirosis is most common during the spring and fall, when the ground tends to stay wet and wildlife activity is high. However, exposure can happen at any time of year. Dogs that spend time outdoors, go on walks in wooded or wet areas, or live near wildlife are at higher risk.
Vaccination Is the Best Prevention
Leptospirosis can be expensive and difficult to treat, but it is preventable through vaccination. The leptospirosis vaccine is widely used and recommended by veterinarians across Ontario. It protects against the most common strains of the bacteria found in this region.
The vaccine is given in two doses, spaced two to four weeks apart. After that, your dog will need an annual booster to stay protected. If your dog has not been vaccinated for leptospirosis or if you are unsure of their vaccine history, we encourage you to book an appointment as soon as possible.
