I appreciate your effort to back up your statement with documentation. I am going to search this also.
I have hunted feral dog packs for years, at the invitation of farmers who experience losses from predation of their sheep and cattle herds. The dog packs are exceptionally dangerous and can only be fired on from a respectable distance, with the capacity to fire on multiple targets fairly rapidly. The problem is well known in agricultural communities.
Wolves are another matter altogether. I have never hunted wolves so have no direct experience with them. However, I have spent time in Northern Greece and villagers there will quickly relate their experiences in dealing with wolves during winter. Many farmers and herders are constantly armed with shotguns specifically to deal with both feral dogs and wolves.
I would like to find some documented cases of wolf attacks in North America, will search my sources. Based on my direct experiences with feral dog packs I would want nothing whatever to do with a wolf pack in the wild, especially in winter.
I believe the dangers created through re-introduction of wolves in the US is being suppressed by advocates of such practices.
