Greg LeMond’s attack dog is staring me down. I’ve made it as far as the living room of the family’s brick manor outside Minneapolis, but now this purebred German shepherd has stopped me in my tracks.

“His name’s Yester, as in ‘yesterday,’ ” the three-time Tour de France winner tells me, rubbing the neck of the dog he’s owned for all of six months. “Aww, he’s okay.”

“He likes you,” LeMond’s wife Kathy chimes in.

I’m not so sure. Yester hasn’t released me from his gaze, and his snout is aimed at the meaty part of my thigh. I try to remember what the Dog Whisperer advises in such situations. Should I stare back into those expressionless eyes or avoid eye contact altogether?

But even the Dog Whisperer rarely deals with creatures such as Yester, who is no house pet but a Level III Schutzhund, a highly trained German-bred police dog, used for security purposes only and costing upward of $20,000. “All I have to do is say ‘throat!’ ” LeMond whispers, “and he’d kill you.” Lucky it is then that Yester only understands commands in German.

It might seem odd to keep a lethal guard dog in the tranquil exurb of Medina, where the locals rarely get up to anything worse than foxhunting. But if you had the kind of enemies that LeMond has acquired over the last few years, you might consider getting some protection too. He has sued everyone from Tim Blixseth, the billionaire who developed the Yellowstone Club, to various sponsors and business partners. He has tape-recorded phone calls with business associates and friends, and, most famously, he’s tangled with Lance Armstrong and Floyd Landis, the only other Americans to have won the Tour de France. LeMond was among the first to suggest that media darling Armstrong might have used performance-enhancing drugs, and he testified at Landis’s doping hearing last May, after a Landis associate threatened to publicly reveal that LeMond had been sexually abused as a child.
