BOZEMAN, Mont. (AP) -- Animal control officers say a woman putting air in her car tires at a Bozeman gas station discovered eight abandoned puppies in a cardboard box that was sealed with duct tape.
Animal control officer Kathy Middleton says six of the 7- to 9-week-old puppies have died since they were discovered Oct. 9. Two others are recovering.
Middleton says the Heeler/Aussie puppies might have been poisoned besides being dumped.
It's unclear how long they were in the box before the woman discovered them, and police are checking security camera footage at the gas station.
Authorities have not released the name of the woman who found the box, which was filled with vomit and excrement.
