What Every Dog Parent in the DMV Needs to Know About Ticks
If you live in DC, Maryland, or Virginia, you already know the DMV is a great place to be a dog owner. Between Rock Creek Park, the C&O Canal towpath, and the countless other trails throughout, there's no shortage of outdoor adventures to share with your pup.
But there's a downside to all that greenery and wildlife: ticks. And in our region, they're not just a nuisance, they're a genuine health threat to your dog.
Why the DMV Is Prime Tick Territory
The Washington metropolitan area has become something of a hotspot for tick activity. The epicenter for studying Lyme disease actually moved from Hartford, Connecticut to Montgomery County, Maryland.
Lyme disease is the most common tick-borne illness in the DMV, with over 3,000 reported human cases in 2024. In Virginia, about 1 in 20 dogs tested positive for Lyme disease in 2025.
Warmer winters, wet springs, and abundant deer and rodent populations all create ideal conditions for ticks to thrive.
And tick season isn't as limited as you might think. While spring through fall is peak activity, black-legged ticks can be active any time temperatures rise above freezing. One Maryland vet noted he actually sees more ticks in October, November, and December than in July and August -5. And a dog's body temperature, which is around 101 degrees, is a magnet for ticks seeking warmth.
The Ticks You'll Encounter in the DMV
Not all ticks are created equal! Here are the main culprits in our region and what they mean for your dog:
Black-Legged Tick (Deer Tick)
This is the big one. The black-legged tick is the primary vector for Lyme disease, along with anaplasmosis, babesiosis, and a form of ehrlichiosis. They're tiny, about the size of a sesame seed, with females showing a reddish-brown abdomen and males appearing solid black or brown.
Lone Star Tick
Recognizable by the single white dot on the female's back (males have white streaks or spots), the lone star tick is an aggressive biter that targets both dogs and humans. It's associated with ehrlichiosis, tularemia, and increasingly, alpha-gal syndrome, a potentially severe allergy to red meat.
American Dog Tick
The largest of the local tick species, the American dog tick can transmit Rocky Mountain spotted fever and tularemia. They're most active in spring and summer, and adult females are the ones most likely to bite.
Brown Dog Tick
This one is unique: it can live and reproduce indoors, infesting homes and kennels. That means year-round risk even for dogs that don't spend much time in the woods.
What Tick-Borne Diseases Mean for Your Dog
The diseases ticks carry don't just affect humans, your dog is at risk too. Symptoms of tick-borne illness in dogs can include fever, lethargy, loss of appetite, lameness that shifts from leg to leg, joint swelling, and in severe cases, nosebleeds or neurological issues.
One of the tricky things about tick-borne diseases in dogs is that symptoms may not appear for 7 to 21 days after a bite, or longer. By the time you notice something's wrong, the infection may have been brewing for weeks.
Protecting Your Dog: A Multi-Layered Approach
Keeping your dog safe from ticks isn't about any single strategy- it's about stacking defenses.
Use Vet-Recommended Tick Prevention
This is your first line of defense. Monthly oral preventives like Simparica, Bravecto, and NexGard work by killing ticks within hours of attachment—before they can transmit disease. Transmission of many tick-borne diseases takes 10 to 12 hours, so a fast-acting preventive can be highly effective.
For dogs that may have seizure risk with oral medications, a Seresto collar is an alternative that lasts about six months -5.
Consider the Lyme Vaccine
There is a vaccine for Lyme disease in dogs, and Virginia has been a leader in its development. A vaccine developed by researchers at VCU is now the most widely used canine Lyme vaccine in North America. The vaccine doesn't replace tick prevention, but it adds another layer of protection—particularly valuable in our high-risk region. Ask your veterinarian if it's right for your dog.
Check Your Dog Daily
Make it a habit. Run your hands over your dog's coat after every outdoor adventure, paying special attention to between the toes, around the head and ears, under the collar, and in the armpits and groin area. Ticks can be hard to spot, especially on dark or long-haired dogs, so feeling for small bumps is just as important as looking. It also wouldn’t hurt to run a lint roller over your dog after they have been outside.
Manage Your Yard
Ticks love leaf litter, tall grass, and brushy edges. Keeping your lawn mowed and clearing leaves can reduce tick habitat around your home. Creating a barrier of gravel or wood chips between your lawn and any wooded areas can also help.
If You Find a Tick on Your Dog
Even with prevention, you might find an attached tick. Here's how to remove it safely:
Use fine-tipped tweezers or a tick-removal tool. Grasp the tick as close to the skin as possible.
Pull straight up with steady, even pressure. Don't twist or jerk—that can leave mouthparts embedded in your dog's skin.
Clean the bite area with alcohol or soap and water, and wash your hands afterward.
Don't use petroleum jelly, alcohol, or a lit match to try to make the tick back out. These methods can irritate the tick and increase the risk of disease transmission.
If you're not comfortable removing the tick yourself, or if it's in a sensitive area like near the eyes or inside the ear, call your vet. They can handle it safely.
When to Call Your Veterinarian
Contact your vet if your dog develops any of these signs in the days or weeks after a tick bite:
Fever
Lethargy or decreased energy
Lameness or limping (especially if it shifts between legs)
Joint swelling
Loss of appetite
Most tick-borne infections in dogs are treatable with antibiotics, especially when caught early. The key is paying attention and acting quickly.
The Bottom Line
Ticks are a fact of life in the DMV, and they're not going away. But with consistent prevention, daily checks, and awareness of the risks, you can keep your dog safe while still enjoying everything this region has to offer. Talk to your veterinarian about the best prevention plan for your dog.
