    Re: Lepto Vaccine & Vet

    Just putting this out there - My sister's lab got lepto in her backyard - in a densely populated town on LI, NY

    So just because you are in an densely populated area doesn't mean you are safe - her vet felt she got it from squirrels

    Re: Lepto Vaccine & Vet

    I don't do the lepto vaccine and I do live near you, I have never had a dog get lepto *knock on wood*. I don't do it because the vaccine doesn't cover all strains of lepto, the vaccine has a high incidence of adverse reaction and the disease can be easily misdiagnosed if you assume the dog had immunity to lepto because he was vaccinated. Also lepto is treatable with antibiotics.

    My apt. complex is not near any farmland as it's a very populated surbabn city 15minutes from New York City.  I don't go hiking, but as I said in my prev post I do see possums at night & the vet did say she can get it from a puddle.  The vet mentioned one outbreak of a dog in my area who only went in his backyard and he got it. 

    But if this has happened in my area, i'm just curious to know why the holistic vets in this area don't recommend it.

    It boils down to relative risk.  The vaccine is a risk and the disease is a risk.  One has to look at several factors:

    • the risk of having a severe reaction to the vaccine (high in small dogs),
    • the risk of contracting the disease,
    • the severity of the disease itself, and
    • the effectiveness of treatment.

    If your dog has 1 chance in 200 of a severe reaction to the lepto vaccine, but only 1 chance in 1000 of contracting the disease, then maybe the vaccine isn't a good idea. 

    Seeing possums doesn't mean that you are seeing infected possums.  I see coyotes, raccoons, possums, foxes, and skunks in my urban neighborhood just outside Dallas.  Each of those species is known to sometimes carry rabies, but a dog with rabies would make the news.  I assure you that we do not have 100% compliance with getting dogs vaccinated against rabies.

    I would ask the regular vet

    • what percentage of his canine patients are not vaccinated for lepto every 6-9 months and
    • what percentage of his canine patients come down with lepto.

    If he can't tell you these numbers, then (from his practice) he really can't tell you how likely an unvaccinated dog is to get lepto in your area.  A story about one dog getting sick says only that the risk of a dog getting lepto is not zero.  Was that dog vaccinated?  A dog vaccinated against lepto can still get lepto if the vaccine was not effective against the right strain(s) of lepto.

    Did her vet actually get a positive test for L. grippotyphosa?  That is the only strain of lepto that is carried by squirrels.

    There are 8 strains of lepto that effect dogs and humans.  We can only vaccinate our pets against 4 of those strains - L. canicola, L. icterohaemorrhagiae, L. grippotyphosa, and L. pomona.

    Opossums can carry L. Bratislava, L. Autumnalis, L. icterohaemorrhagiae - only 1 of which we can vaccinate against.

    Cows can carry any of the 8 strains.  Rats and/or mice can carry 7 of the 8 strains.  Raccoons can carry 6 of 8 strains.

    See this chart for other animals.

    CAUTION:  A dog "fully" vaccinated against lepto can still get one of other 4 strains of lepto.
