Yep.
Ah. A quick perusal of the article sheds just a little light on the subject, in a manner of speaking.
One of the dogs was owned by Mom, the other by Mom’s Boyfriend.
The two dogs got left together in the living room, and the little one somehow “got drawn into” a conflict between the two pooches.
Mom and boyfriend were temporarily detained elsewhere in the domicile, and so were unable to intervene for a period of time.
Certain aspects of the scene now come into focus for me, I don’t know about you.
