A Rottweiler Devoured a Pot Gummy. Then, the 82-Pound Dog Mauled His Owner in a Bloody Hourlong Attack.

Animal experts are warning against feeding cannabis and edibles to dogs after a pet attacked a woman in northern Michigan.

Knewz.com reported that a 2-year-old Rottweiler named "Blau" attacked his owner, leaving bloodstains throughout their home in a gory scene.

Officers arrived at the Gaylord home and found Blau “subdued,” according to an incident report. But the living room carpet was covered with blood.

Then the officers heard an unidentified woman yelling from a bedroom. They found her “laying face up on the bed covered in blood,” the report says.

The woman “could not get up,” it continues. An “immense amount of blood” was on the nearby floor and walls as well.

Authorities determined the woman gave Blau a gummy laced with THC earlier that morning. Then she went to the bathroom.

Blau “ripped her off the seat,” a police report said. That led to a fight which lasted nearly an hour.

The woman finally locked herself in the bedroom, leaving the 82-pound pet to have the run of the house.

The victim was flown by helicopter to Traverse City for treatment. She was in intensive care after surgery, but her sister reported she “almost lost her right arm because of the attack.”

The animal control report posted by The Smoking Gun website notes Blau never acted aggressively toward animal control officers. They used a catchpole to get the animal into a kennel, eventually putting him in quarantine.

The victim’s brother-in-law told relatives he wanted to “come get the dog and kill it,” the report says. Officers assured him that Blau was going nowhere for 10 days due to the quarantine.

Blau was “humanely euthanized," the report adds. That followed another offer to shoot the dog, from the victim’s estranged husband.

“I told him that was against the law,” the report notes.

The victim was released from the hospital and back home, but her father does not blame the gummy for what happened.

The owner was “going through a bad divorce,” the father told authorities, so “the dog was very stressed.”

But the New York Post reports Blau acted aggressively toward a veterinarian during a visit in March, “lunging and growling and trying to bite.”

It’s a bit surprising that the gummy didn’t kill Blau before the rampage.

“THC… is poisonous to dogs," the GoodRx website warns. “While cannabis is generally considered safe for people, no amount is safe for pets."

It adds the effect of edibles or cannabis can vary from one animal to another. But marijuana on its own rarely kills dogs.
