Sadly, dog bites happen every day, some provoked; many others unprovoked.
CBS 5 News is looking into the case of a 150-pound dog that mauled the arm of a 12-year-old boy in Phoenix.
It is now up to a judge whether or not the dog deserves to live or die for its actions.
The boy and his family said the dog, which had been friendly with him before, is dangerous and would probably attack again.
"The dog came up to me and I thought it was sniffing me, and then I heard it snap," said Ismael Pacheco. And, I backed up."
Ismael said he was hanging out with friends in front of the home of a 2-year-old bull mastiff named Roscoe, back on Aug. 4, when the dog ran out of its owner's front door and attacked him.
"It jumped up and grabbed my whole arm, and took me down in the rocks and was shaking his head," Ismael recalled.
By the time Ismael broke free, and Roscoe's owner restrained him, major damage was done.
"Right here he had took a big old chunk of my arm out," Ismael said while pointing at his right arm. "I lost a lot of fat. I lost 50% of my muscle in my tricep and bicep."
Ismael underwent surgery where doctors put his arm back together with staples, stitches and skin grafts.
He'll need future operations to minimize the scar.
The injury will keep Ismael out of school for at least a month, and unable to participate in his favorite sport, mixed martial arts.
"The dog is still living," said Ismael's mother, Dawn Warner. "He's, ya know, he almost took my son's arm off."
Warner said she recently learned this isn't the first time Roscoe has bitten someone, which CBS 5 News confirmed with Maricopa County Animal Care and Control, and she wants to make sure it was his last.
"I'm worried that dog will kill somebody," said Warner. "He needs to be put down."
Roscoe remains under quarantine at a MCACC shelter.
A hearing is scheduled for Aug. 22 to determine if the dog should be declared vicious.
Both Ismael and his parents will be allowed to speak, along with Roscoe's owner.
A judge will make a final determination about whether the dog will be returned to its owner, or whether he's dangerous and should be euthanized.
