Tilly the puppy cost $850 and 6,000 math problems.
To earn the golden retriever-lab mix, 11-year-old Hana Johnson had to meet a challenge from her parents. Johnson's school offered students an independent skill-building program in addition to regular classwork.
"I was working on Level Six and they said we could get a new dog if I got to Level Eight," said Johnson, an incoming sixth-grader. "I put in, like, 80 hours to hit it."
"To tell the truth, I wasn't sure I was on board, but Hana lived up to her end of the bargain," said her mother, Maya Nishikawa. "With my husband and I working remotely and Hana's lacrosse and music activities on hold, we all have time to give to a new member of the family."
But when the Maple Grove mom went looking for a puppy to fulfill her promise, she discovered that puppy love is in short supply.
She submitted adoption applications with various online sites and contacted animal rescue groups, even some in neighboring states, but kept getting rejected.
"Our other dog, Teddy, is a rescue; so is our cat. We're big rescue people; we foster kittens and volunteer at the Animal Humane Society," said Nishikawa. "I believe in giving an animal a chance. But it felt impossible to get a rescue puppy."
Finally, she spotted an ad on Craig's List and snatched up the 9-week-old puppy from a seller in Brainerd, Minn. "She's so playful and sweet. I loved her right away," said Johnson.
