My brother’s childhood best friend has stumbled into a business. He was buying a puppy while visiting a relative in Mexico, and as they were so much cheaper than they would have been at home in the US, he decided to buy the litter and sell the extras. Made a few thousand dollars’ profit in a weekend, so he figured he’d do it again. Now it has grown and he has an employee who sources litters of puppies in Mexico and brings them up for him, and others who are mostly sah moms who sell the puppies for him. They are all making amazing money at it—several of the stay-at-home-moms are earning more than their working husbands, and the friend is trying to decide whether or not to drop out of medical school, since he is already bringing in about what he could as a doctor with his puppy empire.
