Maneewan Kongpreecharat, 57, called the police when she came home to find her dog had brought home and ripped open a bag carrying more than 10,000 pills.
She said on Thursday (July 23) she had taken her husband to hospital at 9am and returned at 11am to find the bag with the pills already in the house. She said she had no idea where Lamphu found the cache.
Police believe it belongs to a drug cartel, which may have dropped the bag off for a client to pick up, but the dog got to it first. Officers said fingerprints have been found on the bag and they will check surveillance camera footage to kick off an investigation.
Six-year-old Lamphu is mostly black with a few white stripes.
