The victim describes the terrifying ordeal said he thinks the dogs were set loose on purpose.
San Leandro police are still looking for the person responsible for letting loose a pair of pit bulls that attacked Larry Osborne and his two rescue dogs, Margo and Mia.
"This attack, which lasted probably about five minutes, was the most vicious thing I've ever encountered," Osborne said. "Leashes in my hand. I can't get my mace. I can't get my knife. I'm in the middle of a battle right away."
A battle that left the three of them hurt, and Margo with the most serious injuries.
"The pit bull had her right here in his mouth and was shaking her like a ragdoll," Osborne said.
Larry says after one dog bit Mia, the other went straight for Margo, locking her in his jaws and not letting go.
"The dogs knocked me down into an embankment like a little levy," he said.
It wasn't until guests at the nearby Marina Inn ran over to help, beating the dogs off with chairs and tables, that the pit bulls finally let go. Witnesses told police they saw the pair of pit bulls come from a blue Toyota pick-up. They're hoping surveillance video will provide clues.
"There's responsibility when you become a pet owner," pet owner Patrick Daly said. "You can't have throw-away dogs."
The Daly family walks a stretch of Marina Park with their dogs regularly looking out for them and each other.
"If their dog is aggressive, they should keep them on a leash at all times because they could attack somebody," said Bridgette Daly.
Police eventually shot and killed both pit bulls after they moved to attack an officer responding to the 911 call.
Larry says he refuses to live in fear and will return to the Marina as soon as Margo and Mila are healthy enough to do so.
"The next time I walk I will have something with me that can I protect them in any situation," he said. "This will never happen to me again."
