Ontario Provincial Police say they have found a third beagle which was stolen from a Lakeshore property last month, but four are still missing.
In a media statement, OPP say the dog was found on July 13 in the City of Windsor.
Police say they are continuing to investigate, and are concerned for the animals' well-being.
The seven dogs were reported missing from a property on Lions Club Road on June 5.
Anyone with information is asked to contact OPP or get in touch anonymously through Crime Stoppers.
The theft occurred amid allegations of animal mistreatment on the property from some members of the nearby community.
The owner of the stolen beagles is the animal control officer for Tecumseh and LaSalle. The thefts prompted the town of Tecumseh to release a statement regarding the condition of the outdoor kennel site where the beagles had been before they were taken.
Laura Moy, director of corporate services and a clerk, said two inspectors with the Ontario Animal Protection Centre had visited the kennel site and found them to be in an "acceptable condition, as well as the dogs."
