The Dirty Shirt Pack was formed by wolves that split off from the existing Smackout Pack in NE Washington.

In July 2015 it was reported that the Dirty Shirt Pack, which had at least six members, killed three adult cows and a calf grazing on U.S. Forest Service land between July 5 and 10 in Stevens County, according to the Washington Department of Fish & Wildlife.

In early 2017, an adult male and a female were collared. The male dispersed to Salmo Pack territory and then up to British Columbia, where he was killed by wildlife managers to protect endangered caribou. The female dispersed to an area north of the Smackout Pack territory in May 2017.

A male wolf from the pack died in 2017 and his death was under investigation.

In July 2017, a wolf dispersed from this family and appeared to be establishing a new territory in northern Stevens County with a wolf from British Columbia.

In February 2018, state biologists collared one adult wolf from the pack. The family had only three wolves at the end of 2018 and did not have breeding pair status for 2018.

State wolf biologists collared an adult female wolf from the family in June 2019.
