A Florida woman says she was reeling over the death of her pit bull, who died after her boyfriend shot the animal when the dog attacked him, according to reports.

Christen Marie, of Miami Beach, confirmed Bentley’s death early Monday in a Facebook post less than 24 hours after the attack near Hawthorne Avenue and 82nd Street.

“He didn’t make it through surgery,” Marie wrote. “I am absolutely devastated, and I don’t think I will ever be the same without him. He was my best friend, my ride or die, my bodyguard and my snuggle buddy.”

Marie’s post also included dozens of pictures with Bentley, a registered service dog who attacked a man identified as Marie’s boyfriend, biting his left arm as he held a box of pizza, WSVN reports.

“Basically, I had a pit bull locked down on my arm,” victim Matt Ellis told the station. “I feared for my life, so I had to shoot it, in its leg. That’s pretty much it.”

Ernesto Rodriguez, a spokesman for the Miami Beach Police Department, told WPLG that cops found a wounded Bentley after the attack around 3:15 p.m. Sunday.

“It went nuts and locked down on my arm,” Ellis told the station, adding that the dog was still attached to his arm when he walked into another room to get a gun. “I actually drug it to the case, opened up the case and grabbed the gun and shot it.”

Ellis then locked Bentley in a room before calling 911. The animal was later taken to Knowles Animal Clinic, but he didn’t survive surgery, according to Marie, who did not immediately return messages seeking comment early Monday.

“I don’t know how I am going to fall asleep without him, or walk in the door without breaking down when he’s not there to jump all over me,” her Facebook post continued. “He went through so much with me, and he was what kept me moving forward every time I wanted to give up.”

Marie said she expects to lie low for a while after Bentley’s death.

“He was my heart,” she wrote. “I’m a mess, and you probably won’t hear from me for a while while I try to cope with this, I don’t really know how I am going to be able to … but I guess I will figure it out.”

Marie had previously created an online fundraiser to help cover the cost of the “emergency surgery” to drain fluid from Bentley’s lungs. The fundraiser had generated more than $750 as of early Monday.

Ellis isn’t expected to face charges in the shooting, WPLG reports. Messages seeking additional comment from Miami Beach police were not immediately returned.
