Study Links Off-Leash Dogs to Rising Bear Encounters in Canada's Parks

Canada's national parks are seeing more tense run-ins between bears and hikers, and a new study says off-leash dogs are a big part of the problem. Researchers are urging hikers to keep dogs leashed after a high-profile grizzly encounter renewed attention on the issue.

A Close Call Puts the Spotlight on Leash Rules

A recent grizzly bear encounter caught on camera in Banff National Park has reignited a conversation that wildlife researchers across Canada have been having for years: what happens when dogs and bears cross paths on the trail. The viral moment showed just how quickly a peaceful hike can turn dangerous, and it's arriving alongside a new study that backs up what many park rangers have long suspected.

What the Research Found

The study analyzed human-bear conflicts across Canadian wilderness areas and found a clear pattern — incidents involving dogs, particularly those off-leash, were more likely to escalate into dangerous encounters. Researchers say an unleashed dog can surprise a bear, provoke a defensive reaction, or even bolt back toward its owner with an agitated bear in pursuit, turning what could have been a non-event into a serious safety incident.

Bears generally prefer to avoid humans altogether, but a loose dog changes that calculation. Dogs can trigger a bear's prey or defense instincts in ways a hiker walking alone typically doesn't, and the unpredictability of an off-leash animal makes it harder for both the bear and the hiker to de-escalate a chance meeting.

Why This Matters Beyond the Rockies

While the featured encounter happened out west, human-wildlife conflict is a nationwide concern, and the same leash-safety principles apply anywhere black bears roam — including across Ontario's provincial parks and conservation areas, many of which see a steady stream of dog-walking hikers every summer and fall. Parks Canada and provincial park authorities alike have long required dogs to be leashed on maintained trails, but enforcement and hiker compliance vary widely.

Wildlife officials say the takeaway isn't to avoid trails with your dog — it's to follow the leash rules that are already in place. A leashed dog stays close, is easier to control if wildlife appears, and is far less likely to provoke or chase an animal into a confrontation.

Tips for Hikers Heading Into Bear Country

Experts recommend a few key precautions for anyone hitting the trails in bear habitat this season:

  • Keep dogs on a leash no longer than a few metres at all times
  • Make noise while hiking so bears have time to move away before you're close
  • Carry bear spray and know how to use it
  • Hike in groups where possible, especially at dawn or dusk
  • Check for posted wildlife activity warnings before setting out

As more Canadians head outdoors with their pets this season, researchers say the message is simple: a leash isn't just about keeping your dog under control — it could be what keeps both of you safe.
