An Identification Mark?

“I noticed there was a big box on the side of the collar and that box was almost directly on her throat,” recalled Luke later in an interview. On March 11, 2017, like every other day, Luke was on time to pick Mya when he noticed an extra collar which at first he thought was an identification mark to classify dogs but then it was something weird which he never noticed in the last one year. Then he was unable to understand that why now all of a sudden this big black band with a box was tightly wrapped around Mya’s neck and what he did next was obvious.
