Jurors deliberated for about four hours before delivering their verdict Friday in the case of Jesse James Clark.
Prosecutors said Clark kept a bulldog named Jagger at his home after the animal was snatched from a Woodland yard in October 2011.
Prosecutors said Clark faces at least three years in prison at his March 7 sentencing, The Daily News of Longview reported.
Two other participants in the plot were sentenced last year.
The dog's owner received text messages demanding that she hand over painkillers and $1,000.
Jagger was later found dead along railroad tracks in Kelso.
