TRACKING

' You can't help your dog find a track, if you don't know where it is yourself '

Some handlers have a real aversion to any stakes and flags being planted anywhere on a track. I can only assume it is a preception they are training for competition and not for the real world. So, in 90 words or less let me explain.

The world is a smorgasbord of odors, if you did a time-lapse video on the place you tracking, you might be amazed at the number of animals that visit these spots during 24 hours. Just because you don't see anything when you lay a track, doesn't mean your's is the only scent in the area. As we've said before, we are not actually teaching the dog how to track but what to track.

You can find should you care to look, more then one way to introduce your dog to the 'scent picture' of a tracking course. The tracking program detailed here, is NOT about competitive AKC or Schutzhund tracking. It is not about 'forced tracking' or remotely connected to footstep tracking. The goal is to have a dog that will maximize the available aroma of the scent trail, whether its in the air or on the ground. We also reserve the right to include off-lead tracking as an option because it works wonders.

FOOD ON TRACKS and Other Things

I think it is important that you know, I believe in using FOOD during the initial part of tracking. I specifically import it into puppy tracking 101, because it is a 'spot-on' super motivator for puppies. I am well aware of the controversy surrounding this practice and eventually I do remove it from anywhere on the tracking course.

Secondly, I will use handler laid tracks, BUT this practice, DOES need a cautionary note. If overused it WILL confuse the dog and they could fail to follow a track not laid by the handler. It is far better to ALWAYS have your dog work a track laid by a stranger but in order to achieve the number of training tracks, within a given time period, requires the effort of a lot of voluntaries.

There is one principle of tracking which is an ABSOLUTE MUST. You MUST KNOW (except for test tracks) where the track is at ALL TIME otherwise you are of little help to the dog. Why? To begin with, you are guiding your dog into a scent field which is already 'polluted' with a cosmic assembly of different odors, everything from grasses to animal droppings, from last night and weeks before. To this, you are asking the dog to follow a SPECIFIC scent trail, a human scent trail, one ABOVE ALL OTHERS that are present. YOU need to know the possible perimeters of where that human scent trail will be and you can't do that unless you know EXACTLY where the tracking course is. I am not advocating foot-step tracking here, that's for Schutzhund competition. I do suggest, markers, flags, stakes or colored rocks to denote the starting scent pad and the corners; not forever, just in the beginning. To have flags or stakes forever would be stupid, not to say counterproductive.


 

THINGS THAT EFFECT TRACKING SUCCESS

 


 

TRACKING RESEARCH

Researchers have been studying dogs tracking performance, both military and civilian personnel. Some of this is hidden away in old archives and takes some looking to find. Whether the work was excuted under the strictest guidelines isn't always understood but it is still interesting reading. Here are some of them.

It was found in scent lineup tests when the scent of identical twins is offered to dogs in succession, the dogs could not differentiate between the twins. In tracking experiments in which two scents are offered simultaneously and mixed up, the dogs were able to distinguish between the two identical twins (Kalmus 1955). These studies show that dogs can differentiate between identical twins, especially when the twins are living apart. However, discrimination is more difficult when the differences were genetic (Schoon and Haak 2002A).
In a study to evaluate the reliability of trained bloodhounds to identify and trail the scent of individual humans in high-traffic areas, eight bloodhounds completed five tests on 48-hour-old trails. Trails were in areas normally encountered in criminal casework—regional parks, college campuses, and urban environments. The trail layers came from different ethnic groups and ages, and trails ranged from .5 to 1.5 miles in length. Using scent pads collected with the Scent Transfer Unit-100 (STU-100), a vacuum-scent-collection device, five experienced bloodhound/handler teams had a success rate of 96 percent with no false identifications. Three novice bloodhound/handler teams had a 53 percent success rate and one false identification. False identifications are defined as an alert on a person whose scent was not present on the scent pad presented at the start of the trail (Harvey). http://www.fbi.gov/hq/lab/fsc/backissu/july2004/research/2004_03_research03.htm.
Dogs can determine the direction of a human odor trail. A study by Hepper and Wells (Chemical Senses 30 (4): 291-298 May 2005) examined how much olfactory information from this trail is required by dogs to determine direction. Six dogs, able to determine direction, were tested on a 21 footstep trail laid on 21 individual carpet squares, one footstep per square, by the same individual wearing the same shoes. Dogs brought in at right-angles to the trail at its centre were able to correctly determine direction better than chance (P < 0.025). Dogs were unable to determine direction when the order of the footsteps was randomized by rearranging the order of the carpet squares. When the individual odor cue was removed, but ground disturbance left, dogs were unable to determine direction, indicating that it was the odor of the individual that was used to determine direction. In the final experiment the number of footsteps made available to the dog was reduced from 21 to 11 and then 9, 7, 5 and finally 3. Dogs were able to determine direction from 5 footsteps but not 3. It was calculated that it takes similar to 1-2 s for the odor information in footsteps to change to provide discernible information that can be used by dogs to determine direction. compiled by T. Jacob at the following website. http://www.cf.ac.uk/biosi/staff/jacob/teaching/sensory/olfact1.html. Steve White, from the Seattle Police Department, wrote an article called Scent in a Bottle or SIAB. You can download it from here, it is worth reading. It is a technique of capturing scent and using it for hard surface tracking.

In, 'Tracking Dog, theory and method' by Glen Johnson, he outlines terminology associated with tracking.

TRACKING DOGS. 'follows close to tracking course with head down/'

TRAILING DOGS. 'follows the body odor with head down and lift their head when tracking into the wind and half way down when in a crosswind.'

FRINGE TRACKER. Works the area in which the scent has been dispersed, often the very edge of the scent strength. They will 'quarter' back and forth across the track, except in a cross winds.

AIR SCENTING Method of following air borne scent.

BLINDFOLD TRACKING. A blindfold is placed over the dogs eyes, requiring him to exclusive us his nose to track

CASTING Method by which the dog will search back and forth for the scent of the track

CROSS-TRACK Tracking course, laid by two separate trackinglayer which cross each other

TRACKING LEG Section of tracking course between each turn

TRAIL Method of following both human rafts and ground disturbance left by the tracklayer

STEP TRACKING Method by which a dog is trained to follow each footstep of a tracking course

FORCE TRACKING Method of compelling the dog to follow ground scent exclusively.

VARIABLE SURFACE TRACK. The tracking course will be laid on various different types of earth, hard-baked soil, pavement, cement, humus soil, grass, tilled soil, sand.


 

TRACKING DIRECTION

Among the extraordinary feats of tracking is a dogs skill to 'cut' a track and correlate the correct direction to follow. It has been suggested the dog determines the direction by the age of the track. Which has never been clarified because at the point in which the dog intersects the track, the age, even within 50' should be relatively the same strength. There is an absolute variable between the beginning and the end of the track or even different areas of the track but we are talking comparing large increments of the course and the dog does not run usual go far before selection the correct course.

I know, I mentioned this was not program about AKC or Schutzhund tracking and again it is not. If you are like me, you may find yourself looking for solutions in other venues. I do want to caution about one point, and this is from direct experience.

Corners on tracks can be overshot or missed all together. You may read about double and triple laying the corners to help rise the dogs awareness of the corners existence. Well, I tried it, in the '80's and I do NOT recommend it. Myself and another handler both experienced where our dogs would actually commit themselves to the wrong direction or backtracking when working an tracking exercise. Now this wasn't a continous occurrence but up until we tried double and triples we never experienced the problem.
