As winter snow melts and outdoor trails reopen across Canada, many pet owners look forward to spending more time outside with their animals. Longer walks, park visits, and weekend adventures quickly become part of daily routines. While the warmer seasons bring exciting outdoor opportunities, they also introduce new health risks for pets.
In 2026, veterinarians are sharing an important reminder with pet families: tick activity has become increasingly unpredictable, and Lyme disease prevention is no longer limited to the summer months. Protecting pets from ticks is now a year-round responsibility.
Across Ontario, pet owners are noticing ticks appearing earlier in spring, remaining active well into autumn, and even surviving during mild winters. Veterinary professionals at trusted animal hospitals in Mississauga are reporting a steady rise in tick-related concerns during routine wellness visits and preventive care appointments.
The Changing Tick Landscape in Canada
For many years, pet owners believed ticks disappeared after the first frost of winter. Changing climate patterns across Canada have reshaped that understanding. Today, ticks are surviving longer seasons and expanding into new regions, creating year-round health concerns for pets.
Blacklegged ticks, often called deer ticks, can become active whenever temperatures rise above approximately 4°C. Even brief warm periods during late winter or early spring may allow ticks to seek hosts. As a result, pets can face exposure during times of the year that were once considered low risk.
Lyme disease develops when an infected tick carrying the bacterium Borrelia burgdorferi attaches to a pet and feeds long enough to transmit infection. While not every tick carries the bacteria, growing tick populations across Ontario have increased the likelihood of contact during everyday outdoor activities such as walks, hikes, and visits to local parks.
Because early exposure is not always visible, preventive care and routine veterinary examinations have become essential parts of responsible pet ownership. Many families now depend on experienced veterinary teams in Mississauga to monitor seasonal risks, provide preventive treatments, and help keep pets protected throughout the year.
Why Lyme Disease Prevention Matters More Than Ever
Lyme disease can affect dogs in several ways. Some pets may show mild symptoms initially, while others develop serious complications if infection goes untreated.
Common signs of Lyme disease include:
- Fever and lethargy
- Loss of appetite
- Joint pain or limping that shifts between legs
- Swollen lymph nodes
- Reduced activity levels
In more advanced cases, Lyme disease may affect kidney function and lead to long term health complications. This is why prevention plays such an important role in modern veterinary care. Detecting risks early and maintaining consistent parasite protection helps reduce the chances of illness and supports lifelong health for pets.
3 Pillars of Lyme Disease Prevention
Preventing Lyme disease requires a consistent and layered approach. Modern veterinary care focuses on protection, early detection, and environmental awareness to reduce tick exposure and keep pets safe throughout the year.
Veterinary-Strength Protection
The most effective way to prevent Lyme disease is to stop the tick before it can transmit the bacteria.
Preventatives: We offer a variety of Health Canada-approved options, including monthly chewables (like NexGard or Simparica) and long-lasting topicals (like Bravecto). These medications are designed to kill ticks quickly after they attach.
The Lyme Vaccine: For dogs who spend time in wooded areas, tall grass, or travel to known “hot zones,” we highly recommend the Lyme vaccine. This provides an extra layer of internal defense.
The “Daily Tick Check” Ritual
Even when pets are protected with medication, daily tick checks remain an important habit after outdoor activities. Ticks often attach in areas that are difficult to see, which means early detection depends on careful inspection.
After walks or playtime outdoors, gently check your pet by feeling for small bumps in common hiding spots:
- Between the toes and paw pads
- Inside and behind the ears
- Under the collar
- The groin and “armpit” areas
Environmental Management
Reducing tick habitats around your home creates another essential layer of prevention. Simple yard maintenance steps can significantly lower tick populations and decrease exposure risk.
Helpful environmental prevention practices include:
- Keeping lawn grass trimmed short
- Removing leaf litter and brush piles where ticks hide.
- Creating a “buffer zone” of woodchips or gravel between your lawn and any wooded areas.
Homes located near walking trails, parks, or conservation spaces in Mississauga may experience higher tick activity, especially during spring and fall seasons. Maintaining outdoor spaces helps protect both pets and family members from unwanted exposure.
I Found a Tick on My Pet. What Should I Do?
If you spot a tick on your pet, the most important thing is to stay calm but act quickly. While there are many “DIY” removal methods shared online, some can increase the risk of infection.
Why Professional Removal is Best
If you aren’t comfortable removing a tick, or if it’s located in a sensitive area like near the eyes or inside the ears, we encourage you to bring your pet into the clinic immediately.
Ensuring Full Removal: If the head of the tick is left behind during a home removal, it can cause localized infection or a painful abscess. Our team uses specialized tools to ensure the entire tick is removed safely.
Why Follow Up Testing Is Important
Removing the tick is only the first step in protecting your pet’s health.
Lyme disease symptoms may not appear immediately. In many cases, pets can carry infection silently for weeks or even months before clinical signs develop. Because of this delayed response, diagnostic testing plays a critical role in early detection.
The 4DX Plus Test: We recommend a simple blood screening that checks for Lyme disease, as well as other common tick-borne illnesses like Anaplasmosis and Ehrlichia.
Early Detection: Since pets often don’t show clinical signs of illness until the infection is well-established, bloodwork allows us to detect and treat these conditions before they cause permanent damage to the joints or kidneys.

Protecting Your Whole Family
Lyme disease is a “One Health” issue. While your dog can’t give you Lyme disease directly, they can carry “hitchhiker” ticks into your home that may later bite you. By protecting your pet, you are helping to protect your entire household.

Frequently Asked Questions (FAQs)
When is tick season in Mississauga?
Ticks can become active whenever temperatures rise above approximately 4°C. In Ontario, this means pets may be at risk from early spring through late fall and even during mild winter periods.
How can I tell if my pet has Lyme disease?
Common symptoms include lethargy, fever, limping, joint pain, loss of appetite, and reduced activity levels. Some pets may not show symptoms immediately, which is why routine testing is important after tick exposure.
Should my dog receive the Lyme disease vaccine?
Dogs that spend time outdoors in parks, wooded areas, hiking trails, or tall grass environments often benefit from Lyme vaccination. Your veterinarian can recommend whether vaccination is appropriate based on lifestyle and risk level.
What should I do if I find a tick on my pet?
Remove the tick promptly using proper technique or visit your veterinary clinic for safe professional removal. Improper removal may leave parts of the tick behind and increase infection risk.
Is tick prevention necessary all year?
Yes. Because ticks can survive during mild weather, year round prevention is now recommended for many pets in Ontario.
Can pets transmit Lyme disease to humans?
Pets cannot directly transmit Lyme disease to people. However, ticks carried indoors on pets may later attach to humans, so protecting pets also helps protect your household.
