Deputy Fire Marshal, Amy Linder demonstrates the animal oxygen mask on her dog, Casey, the Official Fire Safety Dalmatian for the Eugene Springfield Fire Dept. Aug. 27, 2014. The shape of the mask allows clean airflow for the shape of the dog's mouth and nose that a human mask could not provide. Thirty-five of the new companion animal oxygen masks were donated recently to the fire department by the McKenzie Cascade Dog Fanciers Club. (AP Photo/The Register-Guard, Alisha Jucevic)
