Tampa Firefighter Tom Miller's dog Dakota, a 3-year-old mini-Australian shepherd contracted an infection after being attacked and was unresponsive to treatment, according to Tampa Bay Online.
The canine's organs began to fail and died Thursday afternoon.
Miller said that his 26 years as a responder could not prepare him for the loss.
"When it's your pet or family member, it's just not the same," he said. "It was very upsetting. He was covered in blood. He could barely walk. He was stiff and even at the slightest of moves, he would wail in pain."
An animal assistance organization called Frankie's Friends helped to pay for Dakota's treatment.
