When Verline Barthelemy let out her 13-year-old Pomeranian Foxx on 7 August and he did not return right away, she did not expect to find his beaten up body the following day. But sadly, that is exactly what happened.

"He usually came back in two minutes, tops," Barthelemy told the Sun-Sentinel. "I called for him and I didn't hear anything. He'd always come back."

According to Barthelemy, a neighbour discovered Foxx's 7 pound body on a stair leading up to the patio of their condo. The neighbour alerted Barthelemy's boyfriend Ronald W Boisvert, who called 911.

"He didn't deserve to be beaten to death," Barthelemy said of her beloved pet.

As if the gruesome beating of her dog was not enough to handle, a gruesome note was attached to his red-coated body. "WE BEAT IT 2 Death lol! HAHAHA!" the note taped to the dog's body read, according to Pembroke Pines police.

A report by the Saint Francis Emergency Animal Hospital stated Foxx's jaw, spine and ribs were fractured. The small dog's stomach was also displaced, Barthelemy said. "I'm hoping that after the first hit, he was already gone and didn't feel what came next," she added.

The Sun-Sentinel reported that Foxx did not have visible signs of injury and that a necropsy had not been performed. However, police Major Carlos Bermudez cited a veterinarian's report that stated the dog's injured were consistent with blunt force trauma.

Veterinarian Ron Ridge was cited by the Associated Press as saying that Foxx had 10 broken ribs, missing teeth and a broken back. Ridge added Foxx was likely to have been kicked to death.

According to the Washington Post, Pembroke Pines police are actively searching for suspects in the case, but do not believe other dogs are in danger.

"The PPPD would like to let dog owners know that as of now the horrific murder of Foxx, the Pomeranian, appears to be an isolated incident," the department wrote on Facebook. "While we always encourage animal owners to be cautious with leaving their pets unattended, we have no reason to believe that other dogs are at risk at this time."
