Leptospirosis: Is your dog at risk?

29 May

Leptospirosis is a type of bacteria that dogs can pick up from wet, marshy areas or standing water and from eating rodents. The bacteria can either be ingested (from drinking it, from licking paws, from eating infected critters) or it can be transmitted through some type of wound (a small, unnoticed cut on a paw, for example). It results in a disease that causes liver and kidney failure.

It can also be transmitted from dog to human through blood or urine. In humans, the most common symptoms are fever, headache, chills, muscle pain, and in the most severe cases, liver and kidney failure.

In the past, we have included the vaccine for leptospirosis in our distemper combination vaccine (the L in DHLPP). This has never provided great protection, but lepto is one of those diseases that doesn’t get that much attention. There are a bunch of different variations of it (similar to the flu) and the vaccine only works against specific strains. It also, in combination form, only lasts for about six months. We prefer to vaccinate dogs with the DHLPP vaccine every three years, so we have really not been protecting our at-risk patients.

Fortunately, the vaccine has been improving over the years.

Pond-swimming is fun.

Because of this, we are now able to offer vaccine protection that lasts a full year. But this means giving it as a separate vaccine, which is why we are changing our protocol a bit.

Instead of vaccinating all dogs (except those who are sensitive to it– leptospirosis is the most common offender with regards to vaccine reactions) regardless of risk and not protecting them for very long, we will now only be vaccinating dogs who are at risk of contracting the disease.

These are dogs who are exposed to wet or marshy areas, ponds, standing water. Dogs who live on farms, who hike frequently, hunt, or camp are at increased risk. Dogs who have a lot of exposure to areas where wildlife is, especially if it’s a wet area, are at increased risk. Dogs who live in a highly urban environment where rats or other rodents may be a problem are at increased risk. These are the dogs who should be vaccinated against the disease.

Dogs who live a comfortable suburban life, whose life consists of a manicured lawn and walks on sidewalks are at a much lesser risk, and probably do not need to be vaccinated.

The new vaccine is given annually, and separate from the distemper combo. If your dog has previously been vaccinated with the lepto componenent in the combination vaccine, the new vaccine will not need to be boostered. For pups who have never been vaccinated against lepto, they will need to have the vaccine boostered in 3-4 weeks, and then it will become an annual vaccine.

It gets to be a lot, all of these separate vaccines, but we are trying our best to tailor our healthcare to the specific needs of your individual pet. We don’t want to be given vaccines that aren’t needed, but we want to protect those pets who are at risk. If we can prevent a serious disease, especially one that can be transmitted from dog to human, we want to do that. If we can avoid giving unnecessary vaccines to dogs who really don’t need them, we want to do that too. We want to provide the care that best fits your pet and his lifestyle.
