Do you have the links for the dog tracking info?
I could only find this as the source with the most info. . .

Scent dogs used by searchers looking for signs of two missing young girls in Iowa ran around a lake and stopped at the water's edge, the mother of one of the girls said. . . .
The FBI brought two dogs to the area to search Monday night, and the dogs were used again on Tuesday, FBI spokeswoman Sandy Breault said.
The dogs used scent pad samples taken from the girls' shoes and picked up a scent trail, but Breault couldn't say what, if anything, it led investigators to.
Misty Cook-Morrissey, Lyric's mother, told CNN that after smelling the scent pads Monday, the dogs ran around the lake and stopped at the water's edge.
Authorities said Tuesday that they didn't know whether the girls had been at the lake.
"We have their bicycles and we have the purse and that doesn't tell me that they've been there, just that those items are there," Abben said.
The reason I'm asking for a link is because if the dogs track from oldest to newest. . .then why did they stop at the water's edge? The girls weren't in the lake. Could it be that something belonging to the girls went in the lake?

FBI spokeswoman Sandy Breault said the reaction from the dogs Monday night indicated a "strong possibility" the girls had been at the lake, less than a mile from their grandmother's house where they were last reported seen Friday. However, Breault said because there were no confirmed sightings at the lake, authorities couldn't be certain.
I'm discounting MCM's observations and it has nothing to do with her drug history.
Every dog works a little differently and every handler has their own training quirks. While it is possible for an educated observer to make a guesstimate of what a given tracking dog is indicating with their behaviour, only that dog's handler knows for sure.
Each handler puts in thousands of hours of training before their dog is ready to be deployed and during that dog's working career. Handling a tracking dog is like having a second job. Handlers keep meticulous, detailed records of their training logs and deployments so that they can prove in court, if necessary, that what the dog indicated was reasonably reliable.
So, when deciding how much weight to give an observer's testimony, it is important to consider whether that person has ever handled a high level tracking dog, how familiar that person is with the individual dog and what exactly that individual dog's behaviour consisted of.
MCM has, so far as I know, no experience in handling high level tracking dogs. Since the dogs were flown in from out of town, I doubt she had ever observed those dogs before. And she gave her interpretation of what the dog was doing rather than her observations of the dog's behaviour.
So, did the dogs stop at the water's edge? Maybe but that doesn't tell me how they behaved when they stopped. That behaviour would give me a chance to make a semi-educated guess about what the dog's behaviour meant.
I assume that the dog handlers gave their reports to the FBI and that Sandy Breault, as FBI spokesperson, was giving a summary of something in those reports.
Was it an overall summary? I have no idea. Were there any other indications? I have no idea.
Do dogs make mistakes? Sure. But what is the likelihood of two dogs, trained by different handlers, making the identical mistake? I think it's low.
All I know is that the FBI says that the dogs indicated a strong likelihood that the girls had been at the lake but they could not confirm it with any human eye witness testimony.
However, absence of evidence is not evidence of absence.
