Preparing for Battle

Sheepherding dogs on a cattle ranch? That's right, pardner. Joe Fritz (left) and nephew Drew Kuntz look on as Joe's wife, Shannon, trains Border collies to help manage 240 sheep the Fritzes run on their North Dakota ranch to control an invasive flowering plant called leafy spurge. The Eurasian weed contains latex, which burns cows' mouths; enough spurge on pastureland will drive cattle away entirely. Luckily sheep enjoy eating spurge—in fact, they prefer it to grass, says Shannon Fritz.
