The pet had gotten loose and fell through the ice, and three people tried to save the dog but also fell in.
When firefighters arrived late Sunday night, one man and the dog were still in the water.
Ccrews used ladders to reach the man.
The firefighters then climbed down to harness the dog and pull it up to safety.
The three people involved refused medical treatment.
Officials say the dog appeared in good spirits as it warmed up in an ambulance.
