Re Rover, very truewhere I live as well Cluin, free roaming dogs do more damage here running sheep and and deer than any of our native predators. The wolves on Vancouver Island are interbred with dogs too, which also can make them a tad aggressive. Wolves on the southern part of this Island were last reported in the late 1940's about 15 miles from where I live, until fairly recently, when one was shot close by, by a local sheep farmer.
