I used to have a hunting dog that had a great nose so learned a little bit about how they work.
This is JMO because I have no experience with real tracking dogs though.
I believe to be of the best help then LE would need an item from the perp which they of course dont have yet but you do make a good point that officers will just let a dog go looking for a running suspect without that if the suspect had recently run off. We have all seen that happen on TV.
So I am guessing the odors would have to be fairly fresh for a dog to be able to track someone that had been in the area and attempt to follow just that one person. It is a good question though because LE was there very quickly after the shooting. Maybe they did try a dog and maybe it didnt pan out.
Without an article from the perp I think it would be difficult but it is sure worth a try since they pretty much have the exact spot the perp had to have been standing in the latest shooting. You never know if a good dog may pick up a certain odor from that particular perp and get his track.
ot
my furry friend is a coon hound.
After I had her for several weeks I started looking her up -- she is just unreal and different than all the other doggies i have loved
her nose is super doppler
some stuff I learned about her nose!
pure hounds come in a 300 million receptors per whatever it was
coonhounds 275
non hound 150 mill
it is so different
non hounds trail odors hounds track - boy is there a difference hers is completly frantic -- it is not curious it is like she is on a railroad track with her nose
I can tell a person and a dog are somewhere when i cant see them and sure enough a bit later there a human and furry baby come around the corner
all doggies do smell in time they can tell an odor is newer than another smell in the exact same spot
a lot of the time if it is older they will pass if there is an old smell and a newer one ton top of it that is where they will go to be the pardon pun top dog!!
for lady love bug there are different responses based on the size and colorings of other doggies
ones that look like raccoons get a totally different response than ones that don't
without doubt the most fascinating book on our babies I have ever experienced
