Haley McCormack was walking toward the porch of her Davidson County, Tennessee home when all of a sudden her dog, Arlo, leapt into action to save her.

What McCormack didn’t see was a venomous copperhead snake lurking in the corner by the stairs. Arlo jumped toward the snake as it was recoiled back, about to strike, and grabbed it by the tail, shaking it back and forth.

Arlo killed the snake and saved his human, but wound up getting bit in the face three to four times.

McCormack rushed Arlo to BluePearl Pet Hospital in Nashville, where he was given anti-venom, pain medication and CBD oil. His neck and face was very swollen, and his eye was almost completely swollen shut, but he is healing and is expected to make a full recovery.

“To think how much loyalty, and love he had for me, to risk his own life for mine, it’s really special,” McCormack told WTVF. “We’re both lucky to have each other for sure.”

Sadly, Arlo wasn’t the only dog at BluePearl Pet Hospital that day with a snake bite. According to the animal hospital, they’ve already treated more than a dozen snake bite cases this summer alone in their area.

McCormack hopes Arlo’s story will warn people of the dangers of snakes, not just to humans but pets as well.
