Updated at 10:45 a.m.: An email sent to The Bulletin by Lt. Don Wakeman, of the Wilton police, said the dog involved in the Range Road attack was a American Staffordshire terrier, according to the veterinarian who had previously treated the dog.

The American Society for the Prevention of Cruelty to Animals says this breed of dog is correctly identified as a pit bull.

"The most narrow and perhaps most accurate definition of the term 'pit bull' refers to just two breeds: the American Pit Bull Terrier (APBT) and the American Staffordshire Terrier (AmStaff)," the society says.

The American Society for the Prevention of Cruelty to Animals (ASPCA) says the term “pit bull” is vague in its definition.

“... The term doesn’t describe a single breed of dog. Depending on whom you ask, it can refer to just a couple of breeds or to as many as five — and all mixes of these breeds,” the ASPCA says.

One of the breeds that is correctly labeled a "pit bull," according to the ASPCA, is the American Staffordshire Terrier.

The American Kennel Club says this dog is courageous and tenacious, while also being an excellent family dog.

The ASPCA, however, notes that legislation intended to reduce dog attacks by regulating certain breeds of dogs often applies to this breed.

Editor's Note: The Bulletin previously reported the dog involved was a Staffordshire Bull Terrier. That was incorrect, and we regret the error. 

10:00 a.m.: At last night’s Board of Selectmen meeting, Capt. John Lynch of the Wilton Police Department, said the dog involved in Monday’s attack on Range Road was not technically a pit bull.

“It depends on who you ask,” Capt. Lynch said in response to Selectman Hal Clark, who asked whether previous police information on the breed of dog was correct. “It was technically not a pit bull. It certainly looked like a pit bull, though... it was a very large, aggressive dog.”

Capt. Lynch refrained from further explaining the breed of dog involved in last Monday’s attack, saying the breed was besides the point.

“That term, or that name, is stigmatized. It could have been any other breed,” he said.

All previous information provided to The Bulletin by Wilton police had indicated the dog responsible for the attack was a pit bull.

Capt. Lynch also said the department is currently trying to determine the cause of the attack.

“We are still trying to establish how or why it happened,” he said. “It’s an animal, it doesn’t reason like you or I do.”
