A GoFundMe site has been set up to help finance the recovery of a Petsmart employee who suffered grisly injuries during an attack by a pit bull earlier this week.

Sienna Bryden, 22, was mauled by the animal Wednesday while working as a pet groomer at the store's Hyannis branch in Cape Cod, Massachusetts.

The dog, named "Bubba," attacked Bryden she was grooming him, according to MassLive.com.

"While the dog was being moved, for no apparent reason and without warning, the dog attacked the victim and would not let go of her arm," Barnstable police said Wednesday.

The result were horrific wounds to Bryden's arms, wrist and torso that required major surgeries.

Emergency responders found her in the store nearby to a "trail of blood," and she was airlifted to Brigham and Women's Hospital in Boston for treatment, police said.

The animal, which had been involved in an earlier attack in Forestdale in September, was euthanized Thursday.

According to Bryden's GoFundMe page, the owner of the dog had brought the animal in with a muzzle but described it as "sweet as can be." The owner claimed the dog was wearing a muzzle because it had previously attacked another dog, but did not disclose that it had, in fact, mauled a 62-year-old Forestdale woman and shredded her left hand in September, according to Sandwich Deputy Animal Control Officer Walter T. Fagnant Jr.

The dog, Bubba, was voluntarily surrendered by his owners, Clifford and Edith Gardner of Forestdale, and euthanized at around 7 p.m. Thursday, Fagnant told the Cape Cod Times.

Brittany Korsh, who tried to pull Bubba off her mother during the Sept. 5 attack, said she was “heartbroken” for the Petsmart employee.

“This should never have happened,” Korsh wrote.

The GoFundMe account says Bryden's arm was bitten as many as 20 times and that the dog ripped her shoulder from its socket.

Police described Bryden's injuries as "bite wounds to her upper torso, wrist and hand, as well as extensive tearing of the flesh, possible broken bones and a suspected dislocated shoulder."

"She is now home and starting her road to recovery," the site reads. "She is obviously in pain and is tramatized [sic] by the whole accident. Please for the safety of others It is very important for people to please tell the Truth about your dogs when bringing them into grooming facilities."

Barnstable police Sgt. Sean Sweeney said the dog "wouldn’t let go. She has a long road to recovery."

Korsh criticized the Gardners for keeping the dog and Sandwich Police Chief Peter Wack for allowing Bubba to remain at home after he declared the dog dangerous following an Oct. 25 hearing.

Wack ordered Bubba to be muzzled and securely leashed whenever he was outside and off the Cliffords’ property.
