I'm going to post what I tend to say often in these cases where dogs were used but the person was not found....
Dogs are just a tool, and the only time we can truly be sure that any of them were in fact on the right trail is when they lead us to something of significance, like the person, a trail of clothing, items left behind, etc.
In the event that that doesn't happen, then we must, or I should say, should, only take that information as one possibility, not as absolute fact, as there is no way to prove or verify that they were in fact correct.
If you know me on here, you know that I am a huge believer in dogs in SAR work, I also am not going to put full stock in any one resource unless they find me the person I've been looking for. Make sense?
I say this because I am seeing a lot of focus being put on one team's trail being discounted and another team's being latched onto, for really no better reason than that the one makes more sense to people (lost person behavior does NOT always make sense). Since we really know so little about what transpired I caution against focusing too much on any one thing.
MOO, carry on.

Doggie info:
HRD/Cadaver Dogs can be effective from shortly after death to years, decades and centuries later, DEPENDING on training.
Trailing Dogs (these use a scent article) can be effective from minutes to DAYS later, I am still waiting to see a confirmed case of months later. Weather, HEAT, humidity or lack there of, wind all affect scent greatly (as in it eats it up). Those were major factors in this case and many others. (100 degree temps and low humidity are the enemy of scent so to speak). The reality is, the only people I have seen who say they can run a 3 month to year old trail are those who are benefiting from it either financially or for fame. Both of which I feel is not good for the families of these loved ones who the are missing so very much.
The other type of "trailing" dog is the police k9 bloodhound/tracker/trailer. I put these in a separate category because they are generally trained for "hot" trails, as they are used to most often find the bad guy. They are being brought out more and more on MP cases and the issue here is an awful lot of them have not trained on aged trails (24 hrs plus) but many don't seem to think there is a difference and that's an issue, because scent changes, moves, and does all kinds of things as the hours and days go by.
Area search dogs are looking for any human in a given area. They only work well if the areas is free of all other people, otherwise they'll be finding every hiker, biker, and cop along the way.
The part below is Complete speculation
It seems like it would have been hard for them to bring an area dog in given all the LE and public in the area. I have to wonder if they brought trailing dogs in and scented off of something in the car (like the seat), which is done often.
Complete speculation on my part.
