*Sparkling - you see hundreds of over-vaccinated dogs? shock
What exactly do you see?*
Lots! Obviously no two dogs are the same but most reactions to lepto usually happen within 2 weeks - lepto usually effects the kidneys and liver so we're talking things such as jaundice etc
The 'less serious' reactions are sickness, muscle wastage, diarreah, lethargy etc.
Many end up with autoimmune diseases. Allergies. Cancer (long term obviously). Tumours.
I work in a specialist vets. There are two ladies who specialise in homeopathic and more natural ways of treatment, the rest are your usual 'traditional' vets, but as a practice we don't give lepto, however we treat a lot of dogs who react to it.
There have been many dogs that unfortunately have been put to sleep due to their severe reactions.
Honestly, it's not all internet scaremonging. Of course the disease itself is scary, but the chances of your dog catching it is incredibly slim and it doesn't justify putting your dog at the risk of vaccinating against it.
Don't let any vet make you feel guilty for any decision you make. They're meant to help and support you and your animal.
If they don't I highly recommend changing vets!
