A dog was put down after it leapt into a garden and mauled to death a chihuahua in Paulsgrove, England, last week.

The Chihuahua’s heartbroken owners, Jessica Dugan and Alfie Traviss, said they let the pet outside to go to toilet when they heard it “scream.” They rushed outside to find a husky holding their pet between its jaws. Dugan tried to fight off the husky, however, the canine ran away with the chihuahua, named Dior, in its mouth. The husky, named Mika, eventually let go of Dior. CCTV footage of the incident showed the husky running on the street with the chihuahua in its mouth.

Recalling the incident, Dugan said, “It was like losing a family member – I had to witness something killing my dog. I don't sleep, I'm on tablets and I still cry thinking about it. I see it and it's drilled into my brain every night as soon as I close my eyes.”

Dugan added that she and Traviss were furious when the owner of the husky failed to apologize to them. The owner instead told them that she will put the husky down.

“There was no remorse, no care, it was just like it's a normal thing for her. I never knew this woman until this happened,” Dugan said.

Speaking to the News on Tuesday, Beth Roy, the owner of the husky said the canine attacked Dior after escaping over her 6-foot garden fence.

“If Dior was one of my dogs I'd be the same – I'd be devastated. I apologize, but what needed to be done has been done and I can't do anything more. No amount of apology is going to bring that dog back. It's just a freak accident and there's nothing anyone can do about it, or will do about it, because it's nature,” she said.

Roy, who owns eight huskies, three labradors and a Doberman, added that Mika has since been put down.

Meanwhile, a Portsmouth City Council spokeswoman said officials were investigating after neighbors lodged noise complaints.

“There was a joint visit to Roy’s property by the police, kennels staff and RSPCA where all the dogs were assessed and checked for microchips and work to resolve the situation is ongoing,” the spokeswoman said.
