The dog that went missing under mysterious circumstances from an Onoway home last week has now returned home.

The 18-month-old Husky-Collie cross named Diego disappeared from outside its home last Thursday while the owners were out.

In the dog’s place was a note reading: "Smile … you are being watched because you have to be careful. Big Brother is on to you!!!"

Spruce Grove RCMP are crediting concerned citizens and the Facebook page at Parkland County Animal Shelter for helping them locate the dog.

A stranger who lives more than an hour south of Onoway noticed the dog roaming around his neighbourhood, and turned it into the Parkland County Animal Shelter.

Police say the owners were "ecstatic" to see Diego returned.
