Leptospirosis in dogs is a disease caused by Leptospira bacteria, which penetrates the skin and moves to the bloodstream where it can cause infection throughout the body. Leptospira bacteria exist all over the world in water and soil, and they are more common in places with warm climates and high rainfall. When the bacteria infects dogs, it can spread to the liver, kidneys, central nervous system, and reproductive system. Most dogs have strong enough immune systems to fight off the infection, but some are not able to get rid of Leptospirosis from all of the organs. Even when the infection is mostly eradicated, the bacteria can remain in the kidneys and infect the urine. If the liver or kidneys are damaged by the disease, it can be fatal. If you see the signs of Leptospirosis in your dog, consult your veterinarian for a proper diagnosis and treatment. Here is what you should know about the symptoms, causes, and treatments for Leptospirosis in dogs.
Symptoms Of Leptospirosis In Dogs
The symptoms of Leptospirosis in dogs vary and often depend on immune system health. Some dogs that are infected don’t show any signs of illness, and others have mild symptoms and recover on their own. In serious cases, severe illness develops, which can lead to death. The symptoms may also vary based on which organs are infected. Here are some of the signs that can be seen in dogs that suffer from Leptospirosis.
- Soreness or stiffness in muscles
- Difficulty moving or walking
- Loss of appetite
- Increased thirst or urination
- Difficulty urinating
- Difficulty breathing
- Runny nose
- Swollen lymph nodes
- Blood in vomit, urine, stool, or saliva
- Red spots on the gums, mucous membranes, or skin
Causes Of Leptospirosis In Dogs
Leptospirosis in dogs is caused by the Leptospira bacteria, which is present in water and soil throughout the world. For this reason, dogs that drink or swim in water from lakes, rivers, or streams are at greater risk, as are dogs that roam in rural areas, come into contact with infected wild life, or interact with farm animals. Contact with infected rodents may also cause problems, and bites from infected animals can spread the disease. Ingesting infected animals or meat and tissue from contaminated dead animals is another way the disease is transmitted. Leptospirosis is more common in wet environments such as marshy or muddy places with stagnant surface water, though pastures in rural areas that are well-irrigated are also more likely to harbor bacteria. The disease is more prevalent in the Fall season.
Infected urine or any surface that infected urine touches can spread the bacteria, as well. This includes water, food, and bedding that has urine on it. Mother dogs may pass it to their young through the placenta, and breeding sometimes spreads the infection, too.
Leptospirosis can be transmitted between species and can spread from dogs to humans, though this is not the most common means of transmission. Most people are exposed to Leptospira during recreational outdoor activities, usually those that involve water.
Treatments For Leptospirosis In Dogs
Treatment for Leptospirosis in dogs often depends on the severity of the condition. In serious cases, intravenous fluids may be administered to reduce dehydration, and antiemitics or a feeding tube may be used if a dog is unable to keep food down. Blood transfusions may be necessary if a dog is suffering from severe hemorrhaging.
Whether the infection is severe or mild, antibiotics are usually used to fight infection. These are given over the course of at least four weeks. If your veterinarian prescribes antibiotics, make sure to give your dog medication for the full duration of the prescription, even if symptoms improve. Discuss side effects with your veterinarian and monitor your dog’s health as they recover. Usually the prognosis for Leptospirosis is good unless there is severe organ damage. There is a vaccine available for Leptospirosis, but you should ask your veterinarian about its effectiveness and see if it is necessary for your dog before you rely on it as a means of prevention.
