BOISE -- A recent wolf attack in the Boise foothills killed a sheep herding dog.
The one-year-old border collie named Teson was killed May 8, authorities say. Teson was herding sheep through the Upper Hulls Gulch area when the wolf attacked.
Frank Shirts is Teson's owner and has been herding sheep through the Boise foothills for years.
It makes you mad, the sheep herders feel bad about it because they've had him since he was a puppy training him, and it's a asset to me, said Shirts.
Each spring, Shirts relies on two border collies to help guide the sheep, and two great Pyrenees to guard them.
I just like people to know what the wolves will do to you and your animals, they're causing us a lot of problems, always have and probably always will, said Shirts.
Authorities say such an attack isn't necessarily uncommon, but they do want the public to be aware. Wildlife Services says they searched for the wolf by helicopter twice in the past week, with no luck.
Steve Stuebner with the Rangeland Resources Commission says sheep ranchers like Shirts have had run-ins with wolves in the past, but there hasn't been an attack since 2010. He said the attacking animal acted alone.
The kill was one wolf, he said. They had skinned the dog and could tell by the trauma and teeth marks that it was just one wolf, but it was definitely a wolf.
Now, officials are warning those hiking in the foothills, especially the Upper Hulls Gulch area, to keep their dogs close, and watch out for wolves.
His herder had seen four adult wolves and pups, so it's a possibility there could be a pack establishing up there on the Boise ridge, said Stuebner.
Wildlife Services says there's no reason to believe this incident is especially concerning, or that wolves are a growing threat, but ask people who see a wolf to let them know.
Wildlife Services says a few sheep dogs are killed throughout the state each year by wolves.
