Dogs may trigger black bear attacks, says Calgary researcher

A Calgary bear expert says some dogs can causenot stopbear attacks on their owners.

Steven Herrero, a world-recognized bear expert,and another researcher looked at 92 bear attacks in North America over the past five years.Only one of the attacks happened in Alberta.

• Grizzly bear sighting spurs warning in Banff recreation areas

But now he is challenging the idea that dogs help protect their owners.

Because media accounts of events can be incomplete, he said it is difficult to accurately identify how many dogs were on leash versus off leash at the time of the attacks.

But thedata does suggestthat in the majority of cases, it seemed as though the dog ordogs had been running loose at the time of the attack and drew the bear to their owners, he said.

Part of the explanation might be that bears and dogs and their wolf ancestors are age-old enemies, he said.

They are long-evolved competitors."

It also appears that many of the bears weren't focused on the dogs, but came right after the owner, according to Herrero.

He said there's a fairly simple lesson to be learned from the research.

If youre out there in bear country, probably you should keep your dog under control, he said.

Herrero's research has been published in the International Bear News. The article is posted below. On mobile? Click here.
