She's as out of touch of being able to train her dog as she is to be a representative of the State. When we voted to legalize weed, she made a sheriff start a lawsuit to block it on a BS technicality. Used citizen tax dollars against the will of the people who pay them.
More directly, this boast is more of anger issues being attempted of changing the narritive to "go getter attitude." Don't know details of the book, but how this article cites it seems more they she lost her shit over a puppy (honestly being a puppy) killing a neighbor's chicken (not specified if dog was loose or chicken got out), and even that didn't satiate her anger, she went and killed a goat for doing goat things (fertile male who was territorial.)
Honestly, her willingness to be a piece of shit (for various things, feel free to read her wikipedia) is a garner for attention from the worst parts of the GOP to only advance herself, because that's all who she cares about.
What's ~~funny~~ sad about South Dakota is that it's a welfare state. Wouldn't really exist without fed money. Love the message of "we'll accept charity but not offer it if we don't have to"
