On Sunday, Jennifer Minderlein was walking her dog, Nose Goes, on the east side of the University Lake off-leash dog park trail when a beaver attacked the dog.

“She had two decent bite marks and one was really, really deep,” Minderlein said, pointing out two shaved areas on the dog’s right side that were shaved and stitched up. “I was really shocked at how deep her wounds actually were.”

There are warnings about beavers posted around the park. Even if you don’t see the elusive animals, there are gnawed trees everywhere, a tell-tale sign.

Minderlein said she knows where the dens are and tries to avoid them. In this case, Nose Goes was in the woods when the beaver slapped its tail in the water and the dog went after it.

“We’ve walked this park since I’ve had her and had no problems at all. It was the first incident where they actually got us,” she said.

Alaska Department of Fish and Game biologists have been monitoring the problem for years. Biologist Dave Battle said if they get enough reports of aggressive behavior, they’ll have to remove the animals.

“It would mean killing them,” Battle explained. “That’s what we do with beavers. It’s not much good to try to relocate them. Presumably any habitat you would take them to that is good beaver habitat would already have beavers in it.”

Minderlein’s dog wasn’t the only one hurt this summer. Staff at Pet Emergency Treatment on Dowling Road said they patched up two other pups bit by beavers in the past two weeks.

Battle said only one of those attacks was reported to Fish and Game.

“You can report it on social media, you can report it to the news, but one of those calls — it would be nice — if it was to us so we can use it in our decision making process.”

Anyone who’s encountered problems with the beaver can call Fish and Game at 907-267-2257.
