Lyme disease is one of the most common tick-borne illnesses in the United States, and while many pet parents are aware of the risks to humans, it's just as important to understand how it can affect our four-legged companions. With tick season in full swing, knowing the signs of Lyme disease in dogs, and how to protect against it, can help you keep your pup safe and healthy.
What Is Lyme Disease?
Lyme disease is caused by the bacterium Borrelia burgdorferi, which is transmitted through the bite of an infected black-legged tick, also known as the deer tick. While not every tick carries the disease, those that do can pass it to your dog after being attached for 24–48 hours. Dogs that spend time in wooded, grassy, or rural areas are at higher risk, but ticks can also be found in suburban backyards and city parks.
Common Signs of Lyme Disease in Dogs
One of the tricky things about Lyme disease is that symptoms may not appear until weeks—or even months—after a tick bite. Some dogs may never show signs at all, while others can develop serious complications if left untreated.
Here's what to watch for:
1. Limping or Lameness
Dogs with Lyme disease often develop sudden or intermittent limping, sometimes switching legs. This is due to joint inflammation and can be mistaken for an injury.
2. Lethargy
If your energetic pup suddenly seems tired, withdrawn, or uninterested in play or walks, it could be a sign that something's off.
3. Fever
A mild to moderate fever (often between 103°F–105°F) is a common sign of infection. It can also be accompanied by chills or shivering.
4. Swollen Joints or Lymph Nodes
Infected dogs may experience painful or swollen joints. Some also develop swelling in their lymph nodes near the infection site.
5. Loss of Appetite and Weight Loss
Decreased interest in food and gradual weight loss can accompany more advanced stages of the disease.
6. Kidney Complications
In severe cases, Lyme disease can lead to kidney damage. Symptoms may include vomiting, diarrhea, increased thirst and urination, and fluid buildup.
Diagnosis and Treatment
If you notice any of these symptoms or suspect your dog may have been bitten by a tick, contact your veterinarian immediately. A simple blood test can help detect Lyme disease. If diagnosed, treatment typically includes a course of antibiotics, most commonly doxycycline. Dogs usually respond well to treatment, especially if it's caught early.
Prevention Is Key
The best way to protect your dog is through prevention:
Use tick preventatives: Topical treatments, collars, or oral medications can reduce your dog's risk of tick bites. Consult with your veterinarian about which options are best for your specific dog.
Perform daily tick checks: Especially after hikes or walks through grassy areas. Pay close attention to hidden spots like ears, under the collar, between toes, and around the tail base.
Keep grass trimmed and remove brush: Maintain your yard to reduce tick habitats. Consider creating a buffer zone of gravel or wood chips between wooded areas and your lawn.
Vaccination: In high-risk areas, your vet may recommend a Lyme disease vaccine. Discuss whether this option is appropriate for your dog's lifestyle and environment.
Protecting Your Dog
Lyme disease is a serious but preventable illness that requires vigilance from pet owners. With proper prevention strategies, regular tick checks, and prompt veterinary care when symptoms appear, you can significantly reduce your dog's risk. Remember that early detection leads to better outcomes, so don't hesitate to reach out to your veterinarian if you notice any concerning changes in your pet's behavior or health. Your quick action could make all the difference in your furry friend's recovery and long-term wellbeing.
