I notice that the man attacked had his dog with him. Pitts are notorious for attacking other dogs.
As you say, when dogs are on the loose, and there is more than one of them, pack mentality takes over.
Yep, I completely agree with you on dogs, any dog when running with a pack. When we had an Oklahoma ranch still in the family, the primary predators were wild dogs running in packs. If we saw I any dog running loose much less a pack then out came the 30-30 from the pickup rack.
Our best ranch dog was a standard collie, St. Bernard mix. Very protective of the cattle and completely docile otherwise. The barn cats were basically wild but he and the cats would curl up together to sleep.
Which is why this woman was smart not to just rely on her dogs to protect her and to carry a knife.
Oops—wrong thread. There’s another thread running with the story of pitbulls attacking a woman walking her German Shepherds—and her saving herself with the knife that she was carrying.
