Leptospirosis

Leptospirosis is a bacterial infection that occurs most frequently in mild to tropical climates. Reported cases of contracting the disease are more common during late summer and fall, after heavy rainfalls. Cases are far less common in winter months due to the fact that the bacteria cannot survive freezing temperatures. Dry heat kills the bacteria, but it thrives in stagnant water, alkaline conditions, dampness, and mud. While some areas of the country are more apt to this kind of weather, others are not, thus the leptospirosis vaccine remains a non-core vaccine.

Most pets contract the disease when they come into contact with a body of water that is infected with the bacteria, such as a puddle, rainwater, or drain. Other known methods of transmitting the infection include physical contact with saliva, feces, or the infected animal itself. The disease spreads via bodily fluids, through the bloodstream, and usually gets flushed into the kidneys where it often remains and reproduces, infecting the urine. Here it spreads to other animals that come into contact with the infected animal’s waste. The severity of the infection depends on the strength of an animal’s immune system. Younger animals with less developed immune systems are at a much higher risk of death when contracting leptospirosis. Pets that are the most at-risk for contracting the infection are hunting dogs, pets that live in wooded areas, pets that live on farms, or pets who live with other animals.





Because there is a vaccine for leptospirosis and any pet could come into contact with the disease at some point, we do recommend getting your pet vaccinated, especially pets who live in high-risk areas or pets who have contracted the disease once before. Leptospirosis is zoonotic, which means it can spread between infected humans or animals to others.

If you have any questions about the infection or would like to make an appointment for vaccination, please contact our office.

Indications your pet might have leptospirosis: 

  • Dehydration. 
  • Depression. 
  • Excessive drooling. 
  • Fever. 
  • Increased thirst. 
  • Jaundice. 
  • Muscle tenderness. 
  • Red colored urine.
  • Runny nose. 
  • Shivering. 
  • Vomiting.


Pet owners will start to notice signs of a fever within 4-12 days of exposure to the bacteria. We recommend contacting our office at the first indication that something might be wrong. Like most infections, leptospirosis is easily managed when first contracted but can cause more damage the longer it remains in the body; it is also contagious for humans and other household pets.

While there are over 213 strains of leptospirosis, only 8 can infect humans and dogs, and 5 can infect cats. This table shows you the various strains that are contagious to humans and domestic pets, the primary sources the bacteria can be developed from, and other known sources from which you or your pets might obtain the disease:

How is leptospirosis diagnosed?

During your pet’s exam the veterinarian will ask you to describe the symptoms that led you to believe your pet was ill. If a leptospirosis diagnosis is positive, this information will give us a good indication of the progression of the infection and will aide in combating the bacteria. Urine and blood samples will be taken and cultured to determine if any bacteria is present, and the body’s immune system response to infection will be tested by measuring antibodies in the bloodstream; this will help determine the level of infection.

Diagnosing leptospirosis is always done cautiously. Because humans can contract the bacteria from pets, our vets and technicians handle these cases with extreme caution, and we advise pet owners to also take extreme caution when handling a potential case of leptospirosis. Any bodily fluid is a biohazard and needs to be disposed of properly to avoid contamination of oneself, other pets, and wildlife.

Treating leptospirosis

Most pets diagnosed with leptospirosis need to be in isolation to prevent spreading infection to owners and other animals. For severe infection that has progressed beyond the early stages, hemorrhaging and dehydration may have started occurring which will require hospitalization. If a pet comes to our facility with either of these symptoms, they will need 24-hour care and observation until their condition improves.

Leptospirosis is treated with antibiotics for a period of four weeks or longer, depending on the stage of the bacterial infection. During the period that your pet is being medicated, they should remain under close observation and be checked for any negative reaction to prescribed medications. The prognosis for most pets is positive when severe organ damage has not yet occurred. If you notice any changes in your pet’s behavior while taking medication, contact our office immediately.

Testimonials

We took our 5 month old puppy in to get neutered today and had a great experience. They educate you on expenses without making you feel guilty if you decide against extra options. We were able to pick him up 5 hours after dropping him off which was also amazing. Would highly recommend to anyone looking for a vet.

Dr. Genova has been my 4 legged daughter's doctor for her whole life (10 years). He is very personable, informative and kind. I seriously cannot say enough positive things about him.. Why else would I trust him to take care of my baby girl?

The rest of the staff is also very kind. Most of them have changed throughout the years but one thing that hasn't is that you can immediately tell how much they all love animals.

This is definitely one of this places that I wish I could give more than 5 stars to.

We had our first experience at Village at Main Veterinary Hospital today and I couldn't wait to write a review because of how pleased I was with the entire staff and environment. I arrived way early for my appointment but they took me anyway since it was open with no problem at all. As soon as we walked in the door my puppy and I were greeted with smiles and even staff that didn't run the counter came out and greeted and loved on my puppy as well which really put her at ease. Every staff member acknowledged our presence at some point. We were taken back to an exam room and we saw Dr. Tran who was warm and loving toward my puppy, she really took her time and you could easily see that she loves what she does. Dr. Tran covered all of my questions I had planned to ask as well as asked if I had any others. I would highly recommend this clinic to anybody who has had a bad experience at another clinic because it will totally make up for it as it did in our case. Thank you so much again for making us feel right at home and loving what you guys do, I will continue to drive 30 minutes just to have my pooch continue to see you guys :)
