The incident happened Sunday, May 3, near the finish area at Dune Peninsula in Point Defiance Park, according to the Humane Society and witnesses.
The dog involved, identified by witnesses as “Dallas,” was reportedly wearing an “Adopt Me” vest and was accompanied by a Humane Society volunteer at the time of the attack.
A Humane Society spokesperson said the dog had previously been adopted out before being returned to the agency’s care on May 1 — just two days before the marathon incident.
Photos shared online showed a bystander comforting the volunteer while others helped restrain the dog.
The Humane Society later confirmed Dallas was classified as dangerous following the attack and was euthanized.
The Tacoma City Marathon Association also responded publicly, saying it is “carefully evaluating its relationship” with the Humane Society moving forward.
The Humane Society said dogs selected for off-site events typically undergo behavioral and handling reviews conducted by trained staff. »
