How common is it for dogs to not hit on anything outside the house when the missing person has actually been there? I live in the area and we had wind advisories and heavy rain about two days after he went missing. But day #1 was sunny. Are the dogs pretty reliable? (The potential severe weather was a major factor that contributed to the Amber alert, from what I heard).
On another note, I find it interesting that the police haven't advised families to be cautious, watch their kids closely, be on the lookout for predators. I don't know if that's typical, but I haven't heard any warnings and I live within a few miles of his home. I assumed they'd alert the public to be careful if they suspected foul play from someone unrelated to the family. (My very uneducated-on-the-topic thoughts...)
