Canine Leptospirosis - Symptoms and Treatment

The causative agents of leptospirosis are bacteria from the Leptospira genus. The most common strains in dogs are L. canicola and L. icterohaemorrhagiae, but there are others that can also infect your best friend.

Contagion usually takes place through the urine of infected animals, but it can also happen through other bodily fluids. Dogs usually get infected when they drink contaminated water or consume herbs or soil contaminated by the urine of infected animals. Dogs that regularly go to the countryside can also become infected when they walk along ponds or swim in contaminated water.

Whilst this disease is found worldwide, it is much more common in areas with tropical climates because these bacteria thrive in warm, humid environments. They can survive for long periods in bodies of water and other favorable environments. Cold and dry climates, on the other hand, are not favorable for the development of Leptospira, which is why the disease is much less common there.

Dogs that live in areas with lots of wildlife - such as raccoons or squirrels - are more likely to become infected with leptospirosis. Similarly, those who live in very populated cities with large populations of rats and mice are also more likely to become infected.

Diagnosis of infection is often difficult, since most infected dogs display no symptoms. Typically, it is based on the dog's history, physical examination and blood and urine analysis.

To detect leptospirosis, an analysis called a microscopic agglutination test is carried out. This analysis allows for the detection of antibodies that work against the Leptospiragenus bacteria in the dog's blood.

The treatment consists of administering antibiotics, usually orally-administered penicillin, with the aim of killing the bacteria. The dose and duration of treatment must be specified by the vet. In many cases it is necessary to hospitalize the dog for a few days in order to administer IV fluids and help regulate the electrolyte levels in the body.

Those dogs which have suffered kidney or liver damage as a result of the disease will need additional treatment to stop the damage and recuperate the functions of these organs as much as possible.

The owners of dogs affected by this disease have to avoid coming in contact with their pet's bodily fluids until treatment has been successfully completed, since leptospirosis can be easily transmitted to humans.

The best way to prevent leptospirosis consists in preventing dogs from wandering into risk areas, such as ponds, irrigated pastures and muddy areas. Unfortunately, in some places this is easier said than done.

There are also preventive vaccines which work against canine leptospirosis. However, their administration largely depends on where the dog lives and the opinion of your vet, as some vets consider these vaccines to be unessential and avoid giving them to dogs in low risk areas. In any case, vaccination against canine leptospirosis is routine in many countries. Here you can learn more about core and noncore vaccines for dogs.
