As the snow melts and the temperatures finally rise above freezing, London dog owners are eager to hit the trails and off-leash parks. However, spring in Southwestern Ontario also brings the return of some unwelcome guests.

According to the latest 2026 data from Public Health Ontario, blacklegged tick habitats (the species that carries Lyme disease) have expanded significantly across Southern Ontario, including right here in Middlesex County. Furthermore, the wet spring conditions create the perfect breeding ground for Leptospirosis, a dangerous bacterial infection spread through wildlife urine in puddles and mud.

While this sounds intimidating, it shouldn’t keep you and your dog indoors! With a bit of vigilance, the right park choices, and a strong nutritional foundation, you can safely enjoy the beautiful spring weather. Here is your 2026 guide to navigating London’s dog parks safely and boosting your dog’s immune system from the inside out.

Navigating London’s Top Dog Parks in Spring

Ticks wait for hosts by climbing on tall grasses and shrubs, particularly in wooded areas or the fringe borders of trails. When choosing where to walk this spring, opt for parks with wide, clear paths and well-maintained off-leash areas.

Safer Spring Bets in London:

As London’s largest off-leash park, Pottersburg offers a massive, fully fenced area. Sticking to the open, woodchip-covered sections rather than the deep brush reduces tick exposure.
The Thames Valley Parkway: This extensive paved trail system is excellent for on-leash spring walks. Keeping your dog on the pavement and out of the tall grass significantly lowers the risk of ticks hitching a ride.

Areas Requiring Extra Vigilance: Parks with dense woods and naturalized trails, such as Medway Valley Forest Trails or the trails around Fanshawe Conservation Area, are beautiful but carry a higher risk for both ticks and Leptospirosis-contaminated water. If you hike here, spray your dog and yourself with a natural deterrent, keep your dog on a leash, do not let them drink from stagnant puddles, and perform a thorough tick check immediately afterward.

The Nutritional Defense: How Raw Food Supports Immunity

While physical tick checks and vet-approved preventatives are your first line of defense, a robust immune system is your dog’s internal shield against pathogens.

A biologically appropriate raw diet plays a crucial role in immune health. Commercial kibbles, especially those high in carbohydrates and starches, can promote chronic, low-grade inflammation in the body. When the immune system is busy fighting internal inflammation, it is less equipped to handle external threats.

Here is how feeding Raw Pet Food Ontario blends helps your dog prepare for spring:

Bioavailable Nutrients: Our fresh, raw meats provide highly digestible proteins and essential amino acids that the body uses to build strong immune cells.
The Skin Barrier (Omega-3s): A healthy, hydrated coat and strong skin barrier make it harder for pests to take hold and cause irritation. Ensure your dog is getting plenty of Omega-3 fatty acids. Waspu Seal Oil is our go to for our Australian Shepherd!
Gut Health = Immune Health: Roughly 70% of your dog’s immune system resides in their gut. Feeding natural probiotics, like our highly popular Green Beef Tripe, which can help maintain a healthy microbiome, giving their immune system the support it needs.

Local FAQ: Spring Dog Health & Safety in London, Ontario

When does tick season start in Ontario?

Tick season in Ontario officially begins as soon as the temperature consistently rises above freezing (0°C). In 2026, ticks are active right now in the early spring and will remain a threat through the summer and well into the fall.

What are the best off-leash dog parks in London, Ontario?

London boasts several great parks. The Pottersburg-FIDO Off-Leash Area is the largest and highly rated. Stoney Creek Off-Leash Area and Greenway Off-Leash Area are also fantastic, well-maintained options with fenced sections for smaller dogs.

How do I naturally boost my dog’s immune system for spring?

The best natural immune boost comes from a species-appropriate, raw food diet rich in bioavailable proteins and omega-3 fatty acids. Adding gut-supporting superfoods like Green Beef Tripe or our high-quality Beef bone broth can further strengthen their immune response.

Are there ticks at Pottersburg dog park?

Yes, it is possible. While the open, woodchip-covered areas of Pottersburg are generally safer, ticks can be found in any grassy or wooded area in London, including city parks. Always check your dog for ticks after visiting any park.

What is Leptospirosis and is my dog at risk in Ontario?

Leptospirosis is a bacterial infection spread through the urine of infected wildlife (like raccoons and skunks). The bacteria thrive in cool, moist soil and stagnant water, making the wet spring season in Southern Ontario the highest risk time. Do not let your dog drink from puddles or ponds.

How do I safely remove a tick from my dog?

If you find a tick, use fine-tipped tweezers or a dedicated tick removal tool. Grasp the tick as close to your dog’s skin as possible and pull straight upward with steady, even pressure. Do not twist or jerk the tick, and contact your veterinarian for further advice.
