Sean Lowe, of The Bachelor, is working through a seriously scary situation, after the rescue boxer he and his wife Catherine Lowe brought home in January, attacked him multiple times. Lowe said he was sharing the terrifying experience because he figured people would see his injuries or wonder what had happened to the family pet.

The first attack was Thursday, when Lowe, who married Catherine Giudici after choosing her on the 17th season of The Bachelor in 2013, was having friends over for a barbecue.

“Some of the smoke from the barbecue started to drift inside, and our smoke alarm started going off,” he said in a video posted to social media. “And so I grab a dish rag, and I’m going over to — I waft the smoke away from the smoke alarm, because the siren was insanely loud. And as I’m holding the dish rag, Moose comes up and, like, bites it and kind of nips my finger really aggressively, which is something that he does not do.”

Lowe told him no, but it didn’t stop Moose.

“He was biting my feet so hard, he actually put holes in my shoes, and it was hurting my feet,” Lowe said. “I give him like a very stern, like, ‘Moose, no, no.’ And it was right about that moment where he shows his teeth at me and just attacks me. And I don’t mean like, bite and run off, like a lot of dogs do when they’re scared or defensive. I mean, attacks me. And I feel him just kind of ripping into the flesh of my arm. And at this point, I am doing everything I possibly can just to fend this dog off.”

Lowe was finally able to get his pet out the door, when the dog returned for a second attack.The reality star said he was all the more confused because Moose is primarily his, and yet he was “fighting for my life.”

“We’ve only had him for a little under 3 months, but like he’s my dog,” Lowe said. “I walk him. If I run errands, he goes in the truck with me. When I get out of my chair, my kids don’t like it, because he follows me. He doesn’t follow them. Like, it’s my dog.”

Earlier that day, Lowe recalled, Moose had put his head in his lap.

After he managed to send the dog out the door a second time, he saw the deepest cut yet in his arm, with “blood squirting, probably a couple feet squirting.”

“And so my first thought is I think that dog may have nicked an artery,” he said. “And we have the video, which the video is way too violent. I’m not going to share that, but, you hear me saying, ‘This is serious. You got to get me to a hospital. Call Catherine.'”

Lowe said his friends rushed him to get emergency medical care. He left with stitches in five or six different places on his arm.

By the next morning, he said, he realized that he couldn’t have the dog in the house. He was trying to figure out what to do, making calls to no-kill animal shelters, when there was another attack. This time, Lowe was in his front yard, putting his kids in the car with his parents.

“You know, going through a dog attack is pretty darn traumatic,” Lowe said. “Having to relive it less than 12 hours later, seeing that dog running straight at you is a feeling that I don’t think I ever want to experience again.”

Lowe was somehow able to wrestle the dog to the ground and hold it until the cops arrived. He believes the dog would have killed his family members.

“I’ve got a hold of his collar, but I know that he’s ripped my arm open,” Lowe said. “And I just know, like, I’m fighting for my life here, like, I feel like, If this dog gets up, he is going to kill me.”

Another trip to the hospital later, Lowe wondered why that smoke alarm seemed to set off Moose, who was previously gentle enough to sleep with his kids at night.

“I’m grateful it happened the way it did,” Lowe said. “He was a really, really good dog, and we miss him.”
