Simone Biles‘ dog breeder is facing significant backlash for cropping her new Doberman Pinscher’s ears and docking its tail, stating to TMZ Sports that he has received death threats over what he describes as “common practice.”

We spoke with the owner of Regal Empire Dobermans after fans and PETA criticized Biles and her husband, Jonathan Owens, for purchasing a puppy that underwent these procedures.

William Regal is also experiencing backlash, telling us that people have made seriously threatening comments toward him and have attempted to shut down his business.

“This is a procedure performed by licensed veterinarians in the U.S.,” Regal said. “It’s common practice.”

Regal further explained the reasoning behind the procedure, stating that a Doberman’s long tail can break and cause significant pain. He added that ear cropping is done to prevent medical issues like hematoma and can reduce the risk of injury if attacked by other dogs.

Regal, who has been in the breeding business for 10 years, expressed that he does not wish to argue with PETA or critics of the practice but feels that the threats against him and the disrespect shown toward the Olympic champion and NFL player have gone too far.

He added that Biles simply wanted a dog for protection.

“She’s done nothing wrong,” Regal stated, “I haven’t done anything wrong either.”
