Do you trust that your dog would protect you during an encounter with a wild bear?
A new study analyzing 326 documented dog-bear encounters from 1901 to 2023 found that dogs were the aggressors in 54% of incidents. Unleashed dogs were involved in 85% of these cases, complicating safety for hikers and their families.
Why it matters
This research provides critical safety context for pet owners, as human injuries occurred in 70% of cases where a dog returned to its owner after engaging with a bear. The study was commissioned by Canadian park officials following a fatal bear attack in Banff National Park.
Researchers identified that dogs served as the primary aggressor in 54% of the 326 reviewed incidents, compared to only 9% of cases where the dog successfully alerted owners to the bear's presence. Notably, black bears were involved 3.6 times more often than brown bears.

Government administrators responsible for the management and visitor safety protocols of national wilderness areas.
The details
The analysis indicates that dogs frequently provoke encounters that would not otherwise occur, with 85% of studied incidents involving off-leash pets. When dogs engage with bears and then return to their owners, they often bring the animal back to the hiker, leading to a 70% injury rate in those specific interactions. In 36% of total encounters, the dogs failed to provide defensive protection for their human companions.

The Home Front
This research marks a significant shift in understanding wilderness safety, moving away from anecdotal experience toward a data-driven approach to pet management in bear-prone environments. It challenges long-standing assumptions about a dog's role as a protective companion during outdoor recreation.
If you plan to hike in bear country, ensure your dog remains on a leash at all times to prevent them from acting as an unintended lure for predators. Plan your outings by researching local wildlife activity and always maintain situational awareness to protect your family.
The takeaway
The most important takeaway for hikers is that an unleashed dog is significantly more likely to instigate a dangerous encounter with wildlife. Always prioritize keeping your pet physically tethered and under direct control when exploring areas known for black or brown bear populations.
