Mayor of Kingstown - Wikipedia
I saw a story told by the character played by Dianne Wiest to her women female prison inmate students about Native Americans and their dogs crossing the Mississippi.
Thousands of dogs drowned trying to get to their families on the other side of the river as they were not allowed to cross on the barges. This was according to the teacher in the TV series.

Except that the writer who told that story made up the details. The dogs were allowed on the barges.
