They can see the dogs in the brush in and around his property. Tey have shot several of them with tranqualizer darts, but stated the dogs got away before they could catch them. I didn't quite understand that part either.I would think that anyone who was trained with that method would have a better idea of what it would take to bring an animal down.The story stated the dogs were not hungry so they would not go in the live traps.So they are in their own territory, just elusive and probably frightened after having been shot at and chased. The owner is either not helping or may even be hindering the effort based on his statements to the reporter.
