Andres Spancky Raya made his plea on Aug. 9 to one felony count of animal cruelty.
Raya is said to have thrown his dog, named Mary Jane, from a cliff in the 1300 block of Luella Drive into a ravine 145 feet below. Authorities said he threw the dog over the cliff twice last year - on Sept. 26 and Sept. 28.
Both incidents were caught on video by a neighbor, who reported the abuse and helped rescue the dog.
Raya will also serve a five-year prison sentence concurrently with his two-year sentence for an unrelated first-degree residential burglary charge.
