Wanted: missing dog for sale in Islay, Alberta

My dog PJ. is still missing as of Jan. 8th from the Shellbrook area. He is a shepherd rotti cross, black with tan markings and about 10 years old. He acts timid. I have no idea what happened to him or if someone has him. I have spent the last 10 months hunting every way possible, sick with worry, and missing him greatly. I feel like I lost a child and it seems like know one is willing to come forward. Someone out there knows something and they need to tell me, please.
Call me if you know anything. 780 744-. Thankyou.
