A lot of dogs missing in my area?

My dog just disappeared a few weeks ago, my really innocent tender-hearted dog & still hasn't appeared. We saw an ad up in our local store, "Dog missing in Aspen Area" which my area so someone else's is gone too. Some people uo a couple houses had 2 dogs down the road at their old house down the road, those 2 dogs have gone disappeared today. What the hell is going on???
