Leptospirosis is one of the sporadic diseases we see in Northland. It is caused by a bacteria which is spread from the urine of infected animals – usually rats, pigs and cattle but can be spread by other species. 

Dogs are susceptible when they drink water from puddles as the bacteria can penetrate through mucous membranes such as in the mouth or eyes. 

On average we see 3 cases of Leptospirosis a year but there are more cases popping up in the North Island due to the recent flooding.

The initial symptoms of infection are general malaise, inappetence and fever.  The bacteria then enter the blood stream where it attacks the systemic organs – especially the kidney and the liver. 

Unfortunately, by the time a dog is presented to us, they are often extremely unwell. Often, they are glowing ‘yellow’ – skin, sclera of the eyes and gums, due to the liver damage.   Despite intensive hospitalisation, fluids and antibiotics, we do lose a percentage of those patients, although we have also seen many make a complete recovery after a week in hospital. 

Leptospirosis is also a zoonotic disease, which means dogs can pass it on to humans.

The good news is Leptospirosis can be prevented by vaccination. Puppies can be vaccinated as early as 7 weeks of age. Initial vaccination requires 2 vaccinations 3-4 weeks apart and then vaccination is annual, and can be given along with kennel cough and parvo/distemper vaccines.
