Rescue Group Pens Heartbreaking Letter to the 'POS' Who Abandoned Their Dog

This is a tough one to read without shedding a tear.

— -- The letter is titled: "Dear The Callous POS owner of this dog."

Judging from the many shares and likes to the open letter on the Kings SPCA-Rescue page, it seems many people agree with the author's sentiments.

Banjo, as he's come to be called by his rescuers, was dumped on the side of the road by his previous owner according to Kings SPCA-Rescue shelter manager Darlene Laboc. The rescue organization started getting messages and calls about a dog on the side of the road on Saturday and went to see if they could assist on the following Tuesday.

Banjo was still sitting there. Waiting.
