Police believe three men used hot dogs to distract a Labrador retriever and make off with seven guns.
Raw hot dogs were found strewn about a Bridgewater home, where the Labrador resided.
The hot dogs were tracked by police to a supermarket and officers used surveillance video to identify a suspect.
Ronald Elizondo, of Raritan Borough, along with Franklin Township residents Adrian McKoy and Tyshinue Haskins, are charged with burglary, conspiracy to commit burglary and other offenses.
Somerset County's prosecutor believes the guns were the target of the heist.
