The woman escaped with mere scratches when her border collie intervened:
Dog saves woman from cougar attack in living room | British Columbia:
"Angie Prime, 35, was on her living room couch with her 14-week-old puppies Iver and Otto Sunday night when she saw an emaciated cougar enter the room.
“I happened to catch something in the corner of my eye,” Prime told CTV News. “I’ll always remember that face.”
The cat pounced on Prime, but before she was seriously hurt her 11-year-old collie, Vicious, ran to the rescue."
The dog is fine, but authorities killed the cougar. I suspect the puppies were the real target of the attack. Cougars prey on small dogs much more frequently than they do on people.
