[Paws & Awws] Does My Dog Have Leptospirosis?

By — One of many Dog Breeds blogs on

Our poor mini dachshund, Izzy contracted Leptospirosis so I thought I would share a little bit about the condition, it's symptoms, and how to prevent YOUR dog from catching it.

What is Leptospirosis?

Leptospirosis is a sneaky but dangerous bacterium virus strain that is not commonly discussed in the pet world. When contracted, it can affect the body with symptoms that are quite similar to a flu, which is unfortunate because if not detected early Leptospirosis can seriously damage the liver and kidneys.

How Could My Dog Catch Leptospirosis (Lepto)?

Infected wild or domesticated animals including squirrels, skunks, raccoons, mice and rats can be carriers of this virus. Because it is a virus of the affected animal's kidneys, it is typically spread through urine or fecal matter. The virus may be spread by:

Woods, swampy and tropical areas are the areas most likely to harbor this virus. However, don't rule out your backyard or a dog park.

What are the Symptoms of Leptospirosis?

Unvaccinated dogs can suffer traumatically with life-threatening damage to their liver and kidney. Sometimes resulting in death.

In our own case, Izzy was vomiting, having diarrhea, and showing disinterest in everything she normally LOVES to do - even fetching!

I brought Izzy into my vet and they did a thorough examination. Our vet decided to run a blood test to diagnosis or rule out Lepto. Early detection can be life saving! If you suspect your dog might have contracted this disease, push for your vet to take a blood sample to test for Lepto.

How is Leptospirosis Treated?

Depending on the severity of your dog's illness, the most common treatment is a prescribed antibiotic that kills the strain provided by your vet. Your pet will usually be on this for an extended period of time, but luckily, the majority of dogs make a full recovery, as our Izzy did :)

Unfortunately, because this virus can be spread through your infected dog's urine, all household dogs will also need to be treated with an antibiotic. This can be costly, but was well worth it to ensure both of our dogs AND our family remained healthy and safe.


Unfortunately, yes we humans can get it too, so it is important to take precautions when cleaning up after your dog.

Steps to Take:

Although these tips can help and lower your risk in getting this virus, they do not eliminate it entirely. If you feel ill, visit your doctor immediately, especially if your dog has been diagnosis with Lepto.

How Can I Prevent Leptospirosis?

Some lucky dogs carry an antibody against Lepto, which usually means the animal has been previously exposed without showing any symptoms. Cats are believed to have immunity to this virus due to longtime exposure to rodents.

However, your pet can get Lepto again if exposed to the virus, so it is imperative to have your dog vaccinated if your dog is exposed to common areas that can be carriers of this disease.

So how can you prevent an episode?

Izzy is healthy as ever and now, to ensure this never happens again, both her and Romeo receive a yearly vaccination against Lepto now.
