Good boy Umis!
9 year-old Hannah was out on this boat with her cousin when the wind started pushing them far away from shore.
"Put her life jacket back on, got in the water and grabbed the rope and thought she could swim to shore, because she's done that a few times," said Hannah's mother, Jackie Fuszard.
Her mom said Umis, their dog, could tell Hannah was struggling.
"It was scary because the wind was picking up and you really can't do a whole lot when you're on a lake and it's windy," said Jackie.
"After five minutes, I was freezing and getting tired," said Hannah. "And then Umis jumped in the water and he went under and then he came up from under me and I was able to put the rope around him and he pulled us to shore. I think it's pretty awesome that he saved me and my cousin's life."
