SAN DIEGO (KGTV) -- A son dealing with the ravages of his mother and dog being attacked by Pit bulls, says his mom did everything possible to save their pet.

The pair was just walking to the post office when the pits broke through a fence and went straight for the kill.

"It's traumatizing, it's a horror show, just the violence of the whole thing, everything is soaked in blood," said the woman's son, Michael Heider. "I can still smell and taste the blood, we still have blood-soaked clothes that we have to wash, it's just an absolute horror show."

Michael Heider got to his mom and their beloved Yorkie mix, Toast, too late.

"She was holding our little dog and he had just had his throat torn out," Heider said.

Witnesses say the two Pit bulls broke through a fence in the college area Wednesday, ripping Toast from his owner's arms.

"I was so blown away with how brave she was, to get down, literally face-to-face with this giant Pit bull," Heider said. "To try to gouge its eyes out. She's trying to pry our dog out of its mouth, I mean she thought it was going to kill her next."

Toast died on the way to the hospital.

Heider's mom is recovering, with bites all over her body. But, her emotional scars will take longer to heal.

"As bad as the physical stuff is, it's really losing our dog." Heider said. "He was a real member of our family, that's the worst part of the whole thing."

Heider says it's all been a nightmare. Now, he wants Pit bull owners to listen to what happened to his family and prevent it from happening again.

"I just hope that anyone that hears this that's sitting there with their Pit bull going, 'oh that's so terrible, but my pit bull would never do that,' to know that you don't know that," Heider said. "And by the time you do know it could be too late. Someone's animal or someone is going to be dead."

The Pit bulls that attacked Heider's mother and Toast are now in quarantine with animal services.
