Good article.Checked the website for more info and possibly a pic.No luck.I read an article similar to this recently,and the main theory was it was a domestic dog/wolf cross.
Could be. We've had problems with large stray dogs breeding with coyotes, they're called "coy-dogs". They travel in packs and can be extremely vicious. A while back there were some children picking blackberries not even far from their house and were attacked by a pack of coy-dogs. The kids had their lab with them and their dog fought off the coy-dogs. The lab suffered some injuries but was okay and probably saved those kids. Plus, their mom came running with a shotgun.
