LONDON, UNITED KINGDOM: A renowned dog behaviorist has stated that Britain's population of 'mutant' American Bully XL pets are "too dangerous to live" and must be extirpated without any further delay.

Stan Rawlinson wants the breed to be wiped out for good to avoid any deaths of humans by the "intrinsically evil" beasts.

Rawlinson, who has an experience of more than two decades working with aggressive animals, said the controversial breed, loved by celebrities, has "no redeeming qualities". The expert further warned that the canines, which are slowly growing in popularity in the UK, were reportedly bred by shady 'underground' owners in the US to evade dangerous dogs laws.

Why are the breeders allegedly carrying on this illegal act?

According to Daily Mail, Rawlinson firmly believes the breeders are "tinkering with DNA" to enhance the beasts' muscles, size and strength and find a way to avoid bans on dangerous dogs such as the American pit bull terrier.

His claims come in the midst of calls for XL Bullys to be banned in Britain after a disturbing data showed the staggering number of fatal dog attacks related to the breed in the UK since 2021. Two in four fatal dog attacks in the UK in the same year involved XL bulldogs, which later increased to six in 10 in 2022.

The attacks included the high-profile maulings that killed minors Jack Lis, 10, and Bella-Rae Birch, 17 months.

Stan Rawlinson thinks more pets and people's lives are in danger

The 76-year-old thinks that the breeders are playing with fire, and which could jeopardize the lives of many people and pets if urgent action isn't taken to stop the growth of the generically engineered American crosses from reaching Britain's shores.

XL Bullys are usually bred from a combination of many dogs, the main one being the American pit bull terrier, which is banned in the UK. However, as the XL Bully is still not banned, it has allowed the breeders to mix pit bulls with other breeds including the American bulldog, Old English bulldog and the mastiff, to create the new breed and evade the law.

In fact, they are not even registered as a breed by the UK Kennel Club despite their popularity in the UK. They are seen as 'status symbols' and are often purchased for their scary appearance.

What did Stan Rawlinson say?

"These dogs are a danger to women, children and everyone else. They should all be euthanised as a breed. There’s something wrongly wired in these dogs," he told the outlet. "They can just flip. You’re talking nothing to full on and someone is dead in less than 15 seconds."

"You just can’t stop them. These dogs can rip people’s heads off. They’re incredibly powerful. They can open up your jugular veins almost immediately," Rawlinson continued. "They’re too dangerous to be in the hands of the general public. You wouldn’t walk around with a mountain lion on a lead – because that’s effectively what you’ve got."

The expert echoed warnings by PETA members and vets in the country

"We averaged three dog attack deaths a year for the past 25 years. From that, we had 10 last year with up to seven related to the XL Bully. This is only going to get worse," Rawlinson said.

"The type of dogs they're breeding to get these super strong, powerful-looking aggressive dogs are very reactive and have high prey drive. But then start messing with genetics and you’ve got a monster on your hands."

"The XL bully is intrinsically bad as a breed. They're an evil dog because of what's been done to them over in America, where amateur geneticists have tinkered about. There’s a screw loose," he added.

Why doesn't Stan Rawlinson want to go near XL Bully dogs?

"I wouldn't go near one. I've been around all sorts of dogs, even the most dangerous. But these XL Bully dogs are very reactive. They're like the old Roman dogs of war that attacked Britain and helped forge an empire across the continent," Rawlinson stated. "More people are going to die unless we do something about it. "

"They aren't an official breed, it's impossible to track them. The American Pitbull has been banned since 1991 but they are still coming in. That dog is the starting point for the XL Bully and more are being brought in every day," he concluded.
