After competing at Crufts, one of the world's most prestigious dog shows, a three-year-old Irish red setter named Jagger tragically died from what his owner is calling a "malicious poisoning."

In the hours following his second place finish in the sporting group category, the beloved pet — whose show name was Thendara Satisfaction — reportedly collapsed on Friday, March 6 in his home after appearing in the dog show the day before.

One of the dog's co-owners said a vet's preliminary investigation revealed cubes of meat in the animal's stomach had been laced with poison.

"We are led to believe that there's no doubt the dog was maliciously poisoned," Jagger's co-owner Dee Milligan-Bott told 'BBC Radio.' "We are all devastated."

The Kennel Club — which organizes the annual Crufts dog show in Birmingham, England — said they were "deeply shocked and saddened" by Jagger's death, but added they "cannot know the cause of this tragedy" until a toxicology report is released later this week.

"I can only imagine that it was a random act that somebody premeditated and wanted to cause total distress at the best dog show in the world," Milligan-Bott added in her 'BBC' interview, confirming she did not believe her pet was killed by another competitor's owner.
