Lyme Disease Prevention Month: Protecting Your Dog from Ticks in DeKalb County
Lyme Disease Prevention Month: What You Need To Know

As spring warms up the fields and trails around DeKalb, Sycamore, and surrounding rural areas, tick season kicks into high gear. May is recognized as Lyme Disease Prevention Month — the perfect time for pet owners in northern Illinois to focus on safeguarding their dogs from tick-borne diseases, especially Lyme disease in dogs.
At Bethany Animal Hospital, we see firsthand how the beautiful rural landscapes of DeKalb County can increase tick exposure for our canine patients. Here’s what every dog owner in the area needs to know this season.
Why May Matters for Lyme Prevention in Illinois
May marks Lyme Disease Awareness/Prevention Month nationally, and it coincides perfectly with peak tick activity in Illinois. Adult ticks and nymphs become highly active from April through June, with many experts noting heightened risk during warmer, wetter spring months.
In DeKalb County and nearby Sycamore IL, dogs that enjoy hiking, playing in tall grass, wooded edges, or rural backyards face elevated chances of encountering blacklegged (deer) ticks — the primary carriers of Lyme disease. Even suburban yards bordering fields or conservation areas can harbor ticks.
Common Symptoms of Lyme Disease in Dogs
Many dogs exposed to Lyme bacteria (Borrelia burgdorferi) never show obvious signs, but when symptoms appear, they can develop 2–5 months after a bite. Watch for these key indicators:
● Recurrent lameness or shifting leg lameness (often the most common sign)
● Fever
● Lethargy and reduced energy
● Swollen or painful joints
● Loss of appetite
● Enlarged lymph nodes
In rare cases, Lyme can lead to more serious complications such as kidney issues (Lyme nephritis). Early detection makes a big difference, which is why prompt veterinary attention is essential if your dog shows any of these symptoms after spending time outdoors.
Local Tick Risks in DeKalb County & Sycamore IL
DeKalb County’s mix of farmland, parks, trails, and wooded areas creates ideal habitat for ticks. Northern Illinois sees notable activity from blacklegged ticks, which transmit Lyme, as well as other species capable of spreading additional tick-borne illnesses like ehrlichiosis or anaplasmosis.
Dogs that roam freely, hunt, or frequently visit off-leash areas are at higher risk. Even short walks in local parks or your own backyard can result in a tick hitching a ride.
Vaccine vs. Prevention: What’s the Best Strategy?
Many pet owners ask: “Does my dog need the Lyme vaccine?”
The Lyme disease vaccine for dogs can help reduce the risk of infection and lessen the severity of illness if exposure occurs. It is often recommended as a lifestyle vaccine for dogs with regular outdoor exposure in endemic areas like northern Illinois.
However, the vaccine is not 100% effective and does not protect against other tick-borne diseases. That’s why the foundation of protection remains year-round tick prevention — using vet-recommended oral or topical preventives that kill or repel ticks before they can transmit bacteria.
At Bethany Animal Hospital, we tailor recommendations to your dog’s lifestyle, age, and risk level. The best approach usually combines:
● Consistent monthly (or longer-lasting) tick preventives
● The Lyme vaccine when appropriate
● Daily tick checks after outdoor time
How to Remove a Tick from Your Dog — Fast & Correctly
If you find a tick attached to your dog, quick and proper removal is critical. Here’s the safe step-by-step method:
1. Use fine-tipped tweezers or a dedicated tick removal tool.
2. Grasp the tick as close to your dog’s skin as possible — right at the head/mouthparts.
3. Pull upward with steady, even pressure. Avoid twisting, jerking, or crushing the tick’s body.
4. Clean the bite area with antiseptic and wash your hands thoroughly.
5. Dispose of the tick by submerging it in rubbing alcohol or flushing it down the toilet.
Never use matches, petroleum jelly, or nail polish — these old methods can cause the tick to release more bacteria.
