Leptospirosis Can Be Deadly—Is Your Dog Protected?

At Stonebrook Family Pet Clinic, we’re committed to staying up to date on the latest veterinary guidelines so we can give your pets the safest, most effective care possible. One important change you should know about: The Leptospirosis vaccine is now considered a core vaccine, according to the American Animal Hospital Association (AAHA).

So what does that mean for you and your pup? Let’s break it down.

What is Leptospirosis (Lepto)?

Leptospirosis is a serious bacterial infection that can cause kidney and liver failure, and in some cases, even death. It spreads through the urine of infected animals, including wildlife like raccoons, skunks, and rodents—common in both urban and rural areas. Dogs can become infected by drinking from or walking through contaminated water sources like puddles, streams, or wet grass.

The most concerning part? Lepto is zoonotic, which means it can spread to humans too.

Why the Change?

AAHA now recommends including Leptospirosis as a core vaccine because of its growing threat across the country, even in areas where it wasn’t previously common.

Key reasons for this change:
✔️ Lepto has been found in all 50 states
✔️ Wildlife and rodent exposure can happen anywhere—even in your own backyard
✔️ Dogs don’t need to swim in lakes or hike to be at risk
✔️ Modern vaccines are safer and more effective than older versions

What This Means for You and Your Dog

If your dog isn’t already receiving the Lepto vaccine, we’ll likely recommend adding it at your next visit. For dogs already getting it, good news—you’re ahead of the curve!

💉 The vaccine is typically included in your dog’s annual wellness exam
