A Canadian donkey breeder is worried that a grizzly bear that killed two of her animals last month will attack again.

Last month donkeys Jewel and Tabasco were ripped apart by a grizzly bear in Elmworth, Alberta.

And tests by Fish and Wildlife Department officers have confirmed that the same bear killed another donkey near Sundre, Alberta last August.

“It’s not safe. I don’t want it to be a person next time,” donkey owner Christie Olesen told local press.

“It was just awful. I could see their bodies outside my kitchen window.”

The bear was given a tracking collar and relocated to British Columbia after the attack last year but appears to have returned. Although officers say the bear is no longer in the area, Ms Olesen is worried that it will come back again.

“I worry for whoever the bear goes back to. This isn’t your typical bear, it’s not afraid of vehicles or houses,” she said.
