The dog was found inside a duffle bag that had been tossed into a storm drain.
An official at the SPCA in Merced calls the crime despicable. Karen Johnson, Merced SPCA, says "It makes me sad that this is an acceptable form of retribution from people. That they feel this is an okay act to do."
The two teenagers have been arrested and charged with felony animal cruelty, vandalism and conspiracy.
The investigation is ongoing.
