What іѕ Cаnіnе Leptospirosis?

Leptospirosis іѕ аn іnfесtіоuѕ disease саuѕеd bу a tуре оf bасtеrіа called Leptospira. The disease causes ѕеrіоuѕ damage tо the kіdnеу аnd lіvеr аnd may bе fatal іn ѕеvеrе саѕеѕ.

Bасtеrіа аrе passed іn thе urіnе оf infected animals and can survive іn the еnvіrоnmеnt fоr long periods іn wаrm, ѕtаgnаnt wаtеr оr mоіѕt soil.

Wіld animals, іnсludіng ѕkunkѕ, rассооnѕ, ороѕѕumѕ, rаtѕ, wolves, аnd dееr, can ѕрrеаd the іnfесtіоn tо dоgѕ.

Leptospirosis іѕ a disease саuѕеd bу іnfесtіоn with Leptospira bacteria. Thеѕе bасtеrіа can be fоund wоrldwіdе in ѕоіl and water.

How Do Dogs Get Leptospirosis?

Mоѕt dogs аrе infected bу dіrесt соntасt with urіnе from аn infected аnіmаl. Others аrе infected by соntасt with wаtеr or soil соntаmіnаtеd wіth іnfесtеd urіnе.

Lерtоѕріrа can реnеtrаtе thе soft lining of the nоѕе, mouth, аnd eyelid, аnd саn еntеr thе bоdу thrоugh ореn sores аnd ѕсrаtсhеѕ іn thе skin.

After infection, bасtеrіа multiply іn thе bloodstream and thеn move іntо thе tіѕѕuеѕ. Thеу соnсеntrаtе in the liver аnd kіdnеу, саuѕіng еxtеnѕіvе dаmаgе tо thеѕе оrgаnѕ.

However, the dаmаgе саuѕеd bу thе bacteria оftеn leads tо lіvеr failure оr kіdnеу fаіlurе, аnd sometimes bоth. In ѕеvеrе infections, the damage іѕ іrrеvеrѕіblе аnd quісklу becomes fаtаl.

Having a bottle of this in your arsenal is essential for keeping areas, especially outdoors in your yard or garden free from any kind of build-up of urine bacteria.

It comes in easy-to-handle spray bottles, but you can get bigger gallon-size cleaners that can be used on garden sprayers to keep your dogs outside area free of any other animal urine that can occur.

This great video explains the condition in great detail and thankfully, a transcript has been added for your records. Enjoy.

I particularly like this video as it describes and explains everything you need to know about Lepto and interestingly, Dr Becker isn’t keen on the vaccination which is a very strong contrast to what many other vets would say. She does qualify her reasons though, so ultimately it is up to you as a responsible dog owner.

Hi, this is Dr. Karen Becker and today we’re going to discuss canine leptospirosis. canine leptospirosis.

Lepto for short is caused by at least four species of infectious bacteria or Ciro bars.


And we know that there are actually over 20 different ciro bars in existence that could potentially infect your pets.

Leptospira are found in both domesticated and wild animals.

The main carriers of the bacteria are rats, pigs, raccoons, cattle, Fox, skunks and opossums.

In recent years, we’ve seen an increase in canine lepto cases, probably due to better diagnostics, not necessarily because more infections are actually occurring. And so it’s important to know that while leptospirosis is not a new disease, in fact, it’s been around forever.

But in fact, the number of cases that we’re documenting is probably increasing because we’re encroaching more and more on natural habitats and family pets are coming into contact with wildlife known to harbor the bacteria.

Is Lepto Shot Necessary For Dogs?

We also have better diagnostics to be able to identify the disease. The leptospira bacteria is transmitted through urine, which contaminates water sources and can remain infectious in soil for up to six months. Dogs pick up the bacteria through a cut or a break in the skin or when they drink from contaminated water.

Dogs most at risk for leptospirosis are those that spend a lot of time in the water or in areas they get rain or snow runoff. Also, dogs can tend to drink from puddles or ponds. Many dogs with mild lepto infections never show any symptoms.

Generally speaking, young dogs tend to get sicker than older dogs, and clinical signs depend on the age and the health of the dog as well as environmental factors affecting the bacteria as well as the virulence of that particular Sarovar of the bacteria that your dog may have acquired.

When symptoms do occur, they usually show up between four and 12 days after exposure, and the symptoms can include fever, muscle pain, vomiting, diarrhea, loss of appetite, lethargy, depression, and blood in the urine.

The infection primarily affects the kidneys and the liver.

So in serious cases, there can be jaundice, which is a yellowing of the skin primarily in dogs, you’ll see it in the whites of their eyes.

And this indicates the presence of hepatitis or liver inflammation because of the destruction of liver cells by the bacteria.

Blood clotting problems can also develop, which can result in blood in the stool and bleeding from the tissues of the mouth. In rare cases, leptospirosis can also cause respiratory distress and acute pulmonary hemorrhage or lung hemorrhage.

Some dogs that are exposed to love to recover without ever being treated because they never have overt symptoms of lepto and an untreated dog who recovers from leptospirosis can actually become a carrier and shed the bacteria in his or her urine for as long as a year.

The big risk with these particular shedding dogs is the fact that lepto can be zoonotic, which means that humans coming in contact with infected dog urine are at risk of acquiring the infection themselves.

Most of the time, infection causes symptoms and so hopefully symptoms are going to lead you to take your sick dog to the vet.

Dogs that become seriously ill with a lepto infection must be hospitalized to receive antibiotics and appropriate supportive care to control the vomiting and diarrhea as well as provide hydration and nutrition.

Dogs with more mild infections can be managed at home as long as the owner takes appropriate hygiene precautions when cleaning up dog urine.

If your dog has lepto and anyone in your family starts to develop flu-like symptoms, obviously, it’s important that you mentioned to your family physician that a leptospirosis infection could be a possibility.

Leptospira love warm, humid climates and are often found in stagnant water.

Always be mindful of letting your dogs run into places like this. They want to, but it’s important to realize that these places are full of potentially harmful bacteria to your dog.

What Is Canine Leptospirosis

As I mentioned earlier, wild animals can also harbor that bacteria so dogs exposed to potentially contaminated water sources.

Also as well as wild animals are at a much greater risk of developing infections than let’s say city dogs. infection is most common in the summer, early fall, and during flooding.

At home, you can cut down the risk of infection by safely controlling the rodent population in and around your home. If you happen to live where leptospirosis infections are real common, obviously keeping your pet away from ponds, slow-moving water, and sitting or stagnant water is a really good idea.

Now, that being said, I have a warm, stagnant cesspool of a pond that wildlife love to come and visit and my dogs love to swim in every day, all during the summer.

I’m pretty sure that my own pack has absolutely been exposed to lepto bacteria but because I keep their immune systems healthy and because I’m very alert for any symptoms of lepto I’m not overly concerned.

This is what I tell my clients. If you have an amazingly healthy dog that suddenly gets a fever becomes lethargic clearly went from vibrantly healthy to not doing well at all, possibly urinating excessively or urinating bright, fresh. Blood, you need to call your veterinarian immediately and obviously, do a lepto test. lepto is a totally treatable bacterial infection.

And it’s only when a diagnosis isn’t made early enough that dogs can suffer unnecessarily from this bacterial infection.

To Vaccinate or Not To Vaccinate?

There is a vaccine for leptospirosis, but I absolutely don’t recommend it. And I certainly don’t carry it in my hospital. It’s a relatively weak bacterial vaccine that is short-acting and can’t protect against all 20, zero bars of leptospira bacteria.

In fact, it’s actually ineffective for the current Sarovar that’s causing the majority of infections in my particular area. Because the vaccine is a Bactrim, which means it’s a vaccine made for bacterial infections, the vaccine contains this drug add event to elicit a strong immune system response.

Because of this, it also carries a significantly greater risk for adverse reactions. information has recently emerged that the vaccine can actually be one of the causes of the actual disease in dogs, and the vaccine has been linked to early kidney failure in older animals.

I feel because my profession is testing for this ancient endemic infection more frequently than we’re finding more positive animals.

And because of this, we’re stirring a tremendous amount of fear and anxiety in pet owners over this particular bacteria that is far from a new risk for your particular dog.

In fact, it’s been in the environment all along since the beginning of time, and most dogs that don’t live in rural environments don’t have an increased risk of exposure. But that’s still promoting repeated vaccinations for all pets despite the huge vast vaccination risks.

Most importantly, it’s a totally treatable bacteria. So my question is, why would you ever vaccinate for something that’s 100% treatable, I’ve treated about a dozen cases of lepto in my career and have never had a dog experience any lingering problems from the infection.

So I recommend in general that you skip the vaccine. If you live in an endemic area like myself, make sure that your dog’s immune system is strong.

And if you certainly if you want, you can take extra precautions to make sure your dog doesn’t have an opportunity to be exposed to the bacteria.

Now, if you’re like me, you let your dog live a free and happy existence playing in every pod that they find in McKee Creek and simply recognize it.

It’s our job as pet owners to stay alert for the signs of infections.

And certainly, if your pet does begin exhibiting symptoms that you promptly address those symptoms immediately, should they present themselves.
