Dog owners are being urged to be protect their pets from a rare, but potentially fatal disease after a rise in cases was reported by an animal hospital near a town just north of London.

Leptospirosis, also known as Weil's disease, is an illness caused by bacteria that damages vital organs such as the liver and kidneys.

It can affect both humans and pets and is most commonly transferred by urine from infected animals, most commonly rats, mice, cows, pigs and dogs.

In humans Weil's disease can cause symptoms including diarrhoea, headaches and yellowing of the skin, while it is often fatal when it comes to dogs.

Davies Veterinary Specialists, located in Hitchin, speaking to The Comet said it has seen a significant increase in the number of leptospirosis (Weil's disease) cases since the pandemic.

Prior to the pandemic, the team at Davies would manage two or three cases a year, whereas now they are seeing a case nearly every month, according to the news outlet.

The ways dogs can catch Weil's disease, according to the PDSA, include:

  • Other infected dogs
  • Sniffing/licking the ground where an infected dog has urinated
  • Urine from an infected cow, pig or rodent
  • Infected wet ground or fresh water (the disease can live in wet ground and freshwater for several months)

There are vaccinations to help combat against leptospirosis bacteria in the UK (contact your local vet for more information).

Weil's disease treatment

While severe cases of Weil's disease will need to be treated in hospital, most will be treatable by your GP. 

The NHS explains: "You'll usually be given antibiotic tablets to treat the infection. Most people recover in a few days or weeks.

"It's important to finish the course of antibiotics, even if you start to feel better."

You can also take paracetamol or ibuprofen to relieve any aches, pains or a high temperature, the NHS adds.
