Logan Hadley, a firefighter in Utah, was at his station doing paperwork when his team got a call about a dog trapped in a frozen pond.

Logan and eight other firefighters hurried to Steed Park in Clearfield, Utah. There, they saw a black Labrador named Bob struggling to hold on to the edge of the icy pond. The pond, usually a place for fishing when it’s warm, was now covered in ice. It was Sunday, and a big snowstorm had just covered the nearby mountains in snow.

Bob was in the cold water, barking loudly. His worried owner and her three kids were there too, cheering for Bob to stay strong.

Logan, who is 20 and has been a firefighter in Clearfield for almost a year, said, “We’ve practiced for this kind of rescue, but I’ve never really done it until now.” He put on a special insulated suit to get ready to go into the icy water.

Bob had been playing in the snow at the park and jumped into the pond, not realizing it was frozen. Then he couldn’t get out, so his family called for help.

Mark Becraft, the fire chief, said that Bob was trying to swim and find a way out. But soon, he got tired and just rested his paws on the ice. The chief knew they had to hurry because staying in cold water for too long can be very dangerous.

“I was really glad that Bob’s owner didn’t jump in to try to save him, because that could have made things much worse,” said Chief Becraft.

The firefighters tied a safety rope to Logan’s suit and placed a ladder near the slope. This was to help them or to give Bob something to climb on.

A video showed Logan carefully moving down the slope and into the water, trying not to scare Bob. As Logan got closer, Bob started to growl a little.

“Bob, be good!” his owner called out. “Be nice — he’s going to help!” one of her kids yelled.

Logan’s yellow suit helped him float as he moved closer to Bob to rescue him.
