Lyme Disease in Dogs: What Owners Should Know

Lyme disease is one of the most commonly discussed tick borne illnesses in dogs. In Northeast Ohio, exposure risk increases during tick season, particularly in wooded or grassy environments.



For families in Akron, understanding how Lyme disease affects dogs and how prevention works can help reduce risk.

At Copley Fairlawn Veterinary Clinic, we discuss Lyme disease prevention frequently because early protection is more effective than treating complications later.

What Is Lyme Disease in Dogs?

Lyme disease is caused by a bacterium called Borrelia burgdorferi. It is transmitted through the bite of infected ticks, most commonly the black-legged tick, also known as the deer tick.

When a tick attaches and feeds, bacteria may be transmitted into the bloodstream. Not every tick bite results in infection, but exposure risk increases during peak tick season.

Once infected, some dogs show symptoms while others may carry the bacteria without obvious signs.

Lyme Disease Dog Symptoms

Symptoms do not always appear immediately. In some cases, signs develop weeks or even months after a tick bite.

Common signs include:

• Shifting leg lameness
• Joint swelling
• Fever
• Lethargy
• Decreased appetite

One of the most common searches online is “dog limping Lyme disease.” This is because intermittent limping is often one of the earliest noticeable signs.

The lameness may shift from one leg to another as inflammation moves between joints.

In rare cases, Lyme disease can affect kidney function, leading to more serious illness.

Why Does Lyme Disease Cause Limping?

The bacteria trigger inflammation in the joints. This inflammation leads to pain and stiffness.

Dogs may appear normal one day and limp the next. Because the condition can shift between limbs, owners sometimes think their dog has multiple injuries.

If your dog develops unexplained limping and has had potential tick exposure, testing may be recommended.

How Lyme Disease Is Diagnosed

Diagnosis typically begins with a physical examination and review of history, including tick exposure.

Blood tests can detect antibodies to Lyme bacteria. A positive test indicates exposure, but it does not always confirm active disease.

Your veterinarian may recommend additional bloodwork to evaluate kidney function and rule out other causes of lameness.



Because not all positive dogs require treatment, interpretation of test results is important.

Can Lyme Disease Be Prevented?

Prevention focuses on reducing tick exposure and limiting transmission.

Effective strategies include:

• Consistent flea and tick prevention
• Routine tick checks after outdoor activity
• Managing yard vegetation
• Considering Lyme vaccination in higher risk dogs

Vaccination may be recommended for dogs with frequent outdoor exposure in tick-prone areas.

You can learn more about preventive options on our Vaccinations page.

For broader tick prevention guidance, see our Flea & Tick Control page.

Is the Lyme Vaccine Necessary?

Whether to vaccinate depends on your dog’s lifestyle.

Dogs that hike, hunt, or spend time in wooded or grassy areas around Akron may benefit more from vaccination.



Indoor-only dogs with minimal exposure may have lower risk.

The decision should be based on individual exposure patterns and discussion with your veterinarian.

Vaccination is not a substitute for tick prevention. Both strategies may be recommended together for higher-risk dogs.

Can Dogs Spread Lyme Disease to People?

Dogs do not directly transmit Lyme disease to humans.

However, a dog that carries ticks into the home may increase household exposure risk.

Tick prevention protects both pets and people.
