Jake suffered puncture wounds and lacerations during his ordeal
A MAN has saved his pet dog from a shark attack by jumping into the water and punching the predator in the neck.
Greg LeNoir took his 28-month-old, 6.3kg rat terrier Jake for his daily swim at a Florida marina when a 1.5m-long shark surfaced and bit into the dog.
Mr LeNoir yelled and jumped into the water to save his dog, the Miami Herald reports.
''I clenched my fists and dove straight in with all my strength, like a battering ram,'' Mr LeNoir, 53, said.
"I hit the back of the shark's neck. It was like hitting concrete."
Both man and dog made it safely back to shore.
Jake suffered puncture wounds to his abdomen, chest and back and lacerations on his right side and front left leg.
"Jake's doing great," Mr LeNoir's brother, Phillip, told the Miami Herald.
"And I still can't believe my brother jumped in the water and punched a shark."
