I went to go educate myself on dog tracking and found out there is tracking and trailing. One (usually?) has the handler pulling the dogs nose back on the trail. The other allowing the dog to sniff wherever it wants. For instance, if someone being tracked went east, circled around, but was now west of you... the dog can smell their scent off the wind so it seems to me like it's best to let the dog sniff where it wants, and not just force its nose onto the path.
It also says that it's easier to track on soft surfaces versus paved. We all know that the area Jason's car was found wasn't paved, it was all soft ground so this is supposed to be easier for the dog. Also this is out in the country, not in the middle of NYC where numerous scents could make tracking more difficult. Which makes me question this again...
why did the track abruptly stop? Especially since it seems like it was one of the better surfaces to track. I wonder what method was used? Using the lead to force the dogs nose onto the path the
human (who can't smell as well as a dog) thinks the dog needs to stay focused on? What if the dog is thinking... 'Tracker dude... I smell him over there. Quit yanking my dang nose down! I'm ONTO something here and it's no longer strongest right under my nose!'.
And yes, the tracking people are experts in this matter, but the article raises a really good point....
If the dog's nose strayed from the prescribed height above the track, his nose was promptly forced back into it without anyone ever examining the reasons for the behavioral change. It was automatically presumed that the dog was outside of odor. Many people believe that the dog must be within inches of the track to actually smell the odor. I believe that perception comes from our own scent-limited world and false rationalization. Nothing could be further from the truth, and simple tests have proven time and again that most dogs can detect odor from a fixed location and at a variety of distances — from inches to yards and more. Consider this question: if it is proven that a dog can detect odor from either ground disturbance or from the human that created it, and from more than mere inches of the physical track, why must a dog's nose be forced into said track?
Makes me more curious about how the tracking was done, and how exactly the handlers handled the dogs. Only one way to know and that would have been to witness it yourself.
