Lois Whitman jokes her life "went to the dogs" years ago.
On a recent Saturday morning, she enticed a tiny Yorkshire Terrier and a Brindle Boxer with a piece of meat and then instructed them to ignore it.
"Leave it!" she said firmly, rewarding the dogs with a quick lick of her finger when they obey.
"This command could literally save your life," Whitman tells the two dogs' owners during an obedience class in the back room of Sandusky Feed & Supply. "If they can learn to leave food alone, they can learn to leave anything alone ... whether it be kids, cars, bikes, the TV remote or your shoes and socks."
