Leptospirosis is a bacterial infection that affects dogs and people. 

It’s caused by the bacteria Leptospira interrogans, 

which causes kidney damage and even death in some cases.


Your dog can get leptospirosis by coming into contact with contaminated soil or water, 

or by eating infected animals or rodents.

Can dogs get sick from the leptospirosis vaccine and what are the risks?


it’s possible for dogs to get sick from the leptospirosis vaccine. 

But you shouldn’t worry too much about it! 

There are a few things you can do to help minimize your dog’s risk of getting sick from the vaccine.


First, make sure your dog gets a complete and thorough vaccination series. 

The leptospirosis vaccine is given over several days and is administered at least two weeks apart from each other. 

So if you’re giving your dog a series, 

it’s important that all injections are given at least four weeks apart,

and preferably eight weeks apart,

to maximize your dog’s protection against this deadly disease.


Second, make sure you have up-to-date rabies vaccinations in place before administering the leptospirosis vaccine. 

You should also watch out for any signs of illness (such as fever) immediately after giving your pet the vaccine, 

but this is very rare in dogs that have received their full series of vaccinations.

Can dogs die from the leptospirosis vaccine?

Yes, dogs can die from the leptospirosis vaccine.

The leptospirosis vaccine is a preventative measure for dogs that have been exposed to leptospirosis in the past. 

The vaccine contains a weakened form of the bacterium that causes leptospirosis and can cause an allergic reaction. 

The skin of your dog will be injected with this weakened version of the bacteria, 

which prompts their immune system to produce antibodies against it.

watch for signs such as vomiting, diarrhea, and increased thirst or urination. 

If you see these symptoms in your dog after vaccination, 

take them to your vet immediately for a checkup.
