The police chief of  Duluth Townships Police Department said he found the dogs, and when he went to return the pups to their rightful owner, he smelled a strong marijuana odor from the trailer.

A search warrant was issued last Thursday and led to a bust of a $100,000 marijuana operation.

A father-son team had 77 marijuana plants, grow equipment and video monitoring devices.
