The dog’s face was dripping with blood after the horrific attack around 9.20am on Larkin Street as the victim lay nearby.

Police arrived on the block between Eddy and Turk streets to find the victim severely bleeding and the dog standing right beside her covered in blood.

San Francisco Animal Care & Control has since taken possession of the dog’s remains as authorities investigate what may have triggered the violent attack, according to KTVU.

The animal died on Larkin Street shortly before animal control officers arrived, police confirmed.

Investigators are now looking into whether an underlying medical condition or exposure to a foreign substance could have contributed to the dog’s behavior and sudden death.

Dr. Thomas Jansen, an emergency veterinarian with MedVet, told KTVU that certain neurological illnesses or toxins can cause dogs to behave in ways that are dramatically different from their usual temperament.

“Sometimes in the ER, we see dogs that have altered mentation’s because of either severe neurologic disease or some kind of a toxin that they got into,” Jansen said. “And indeed, they’re acting in a way that’s completely foreign to their normal behavior or temperament.”

Authorities have not determined whether either possibility played a role in Tuesday’s attack.

Jansen also expressed concern for the injured woman as she fights for her life.

“With everything else going on in the world, just seeing that, I immediately just felt a visceral [sadness] and hope she’s getting the care that’s needed and hope she makes a full recovery,” he said.
