A Stevenson man accused of blowing up his dog pleaded not guilty Thursday in Skamania County Superior Court.
Christopher Wayne Dillingham is charged with possessing an explosive device, reckless endangerment, a fireworks violation and animal cruelty.
If convicted, the 45-year-old could face up to 20 years in prison.
KATU reports Dillingham remains in jail on $500,000 bail.
He was arrested early Aug. 5 after neighbors reported hearing the blast. Deputies found a yellow lab, named Cabela, decapitated.
According to court papers, Dillingham said he killed the dog because an ex-girlfriend had "put the devil in it."
He also said he was preparing for the rapture.
