Beavers that have attacked at least two dogs — one fatally — in a Red Deer, Alta., park will be trapped and killed.

The attacks happened last week when the dogs swam after the beavers at Three Mile Bend, an off-leash park in the central Alberta city, said parks superintendent Trevor Poth.

One dog reportedly died from blood loss. A handful of other beaver run-ins have also been reported but not confirmed, said Poth.

Heather Markiw said that one of her 10-month-old shepherd-cross dogs needed stitches after a scuffle with a beaver on an island in a park pond last week.

Poth said this is the first time there have been any problems with aggressive wildlife in the park's 20-year history. About six to 12 beavers live at Three Mile Bend, he said.

Because of the gravity of the incidents, the beavers will be trapped and killed, Poth said on Wednesday.

Beavers are not usually aggressive unless threatened by other animals, he added.
