Why Even City Dogs Are at High Risk in the New 2026 Tick Forecast

We often think of ticks and tick-borne diseases as a summer concern, something to prepare for once the sun is shining and the flowers are in full bloom. However, the Companion Animal Parasite Council (CAPC) recently released its 2026 Annual Parasite Forecast, and we need to talk about it!


Their findings highlight an important shift in tick populations, suggesting that the “off-season” is becoming a thing of the past.


For those of us dedicated to protecting our dogs from the dangers of ticks and tick-borne diseases, understanding these shifting tick population patterns is key. This allows us to make decisions focused on prevention and proactive wellness.


The 2026 report highlights that tick-borne pathogens are no longer confined to the traditional hot zones. A mix of climate change, reforestation, and the movement of pets across borders has enabled ticks to spread into new areas at a surprisingly fast pace.


In particular, Lyme disease, carried by the blacklegged tick, is pushing further west and north. While the Northeast and Upper Midwest are still considered high risk, states like Ohio, Kentucky, and West Virginia are seeing some of the most significant population booms.


For those living in northern border states and Canada, the report shares that these ticks are showing up in places they previously weren’t found.


The forecast isn’t just about the “big names” like Lyme and Anaplasmosis. It also brings attention to several emerging threats that every pet parent should have on their radar. A newly confirmed tick-borne bacterium, Rickettsia finnyi, has been detected in the Southeast and Midwest.


This pathogen mimics the signs and symptoms of Rocky Mountain spotted fever (RMSF). In fact, Rickettsia finnyi may trigger a positive test result for RMSF, making diagnosis challenging.


The lone star tick itself (the tick responsible for the spread of RMSF and Ehrlichiosis) is a major part of the 2026 story.

Historically found in the South, it is now spreading quickly into the Upper Midwest and New England, bringing these tick-borne diseases to areas that haven’t traditionally dealt with them.


Meanwhile, the brown dog tick, a species uniquely adapted to living and thriving in homes and in kennels, is moving northward from the Southwest into Colorado and Utah. Their ability to survive indoors means their lifecycle and the transmission of disease will continue year-round, regardless of the temperatures or weather conditions outside.


So, what does this mean for us as pet parents? The biggest takeaway is the importance of continuous, year-round tick protection. Because many tick species have longer activity periods, with adults active in cooler months and juveniles thriving in the summer, a seasonal approach leaves a dangerous gap in your pet’s defense. Additional lessons include:

  • Annual Screening: Testing isn’t just about diagnosis; it’s a surveillance tool to catch even the slightest changes before they escalate into a serious situation. A positive antibody test tells you that a tick bite occurred, letting you know that your current prevention strategy might need an upgrade and warning your vet that there could be additional problems in the works.


  • Environmental Management: Since wildlife like deer and white-footed mice act as carriers of these diseases, keeping your property clean means making it less “tick-friendly.” Clear tall grass and brush regularly, and avoid leaving piles of sticks or other vegetation that attract visitors.


  • Risk-Based Vaccination: In areas where Lyme is considered high-risk, vaccination can be a powerful tool to reduce the severity of the disease if your dog is exposed.


By staying informed of the risks and prioritizing year-round tick prevention, we can help our pets stay happy, healthy, and adventurous, no matter where the trail leads.
