I suppose this will become a bigger problem when more people realize they can't afford to feed Fido and turn him loose. Dogs have a natural instinct to form packs. I can definitely see a problem with packs of feral dogs roaming around in the future.
This isn't the first and won't be the last... It reflects the attitudes of the majority on the rez with clear disregard for their own people and lands and irresponsibility of their character. They want to blame whites for everything but I don't remember my ancestors dropping of horse trailers of feral "rez dogs" to attack our native brethren. They did this to themselves and their natural tendencies to not take care of themselves led to this travesty. My thoughts are with these families of the attacked and slain by dogs on the rez. Watch how not one NATIVE will be held accountable (police, dog owners, residents, etc) and how WHITEY will some how have plotted against the REDS again...sad.
