The dogs didn't die. They weren't even hurt. They played with the polar bear. Finally the bear went on it's way after a few nights of visiting. Alls well. They have owners, they took the pics.
I saw the email on this with several pics. Apparently the bear came back several nights in a row to play, them it simply went on it's way. By the way to those who think the poor dogs are chained. They were. These are dog sled dogs.
