About Our Dogs
Ongoing research has determined the efficiency of using explosive K9 search teams screening the contents of cargo containers and the like. Our searches have shown success to applied airborne sampling methods used to detect minute traces of explosives, potentially carried by terrorists posing as passengers.
High-tech solutions have been proposed to scan such containers by x-rays or mechanical trace detection devices, but these solutions cost millions of dollars per installation. If it is possible, to sample the interior of cargo containers for trace explosives without opening them then the cost could be only thousands of dollars, not millions, per instrument. A single individual, for example, using a trained detection dog, would be conceivable to test many cargo containers for trace explosives in a given work day. This approach can be applied to sea, rail, and truck cargo containers.
Our dogs work for the love of work, with their reward simply to please their handler and get their reinforcement. Our K9 units display an ability to deploy with a moment's notice in an emergency response requirement. We are extremely mobile and always keen to accept a search role.
The canine nose
The dog’s nose consists of a bony nasal cavity that is divided into two separate chambers by a bony and cartilaginous nasal septum. Within each of the cavities are the turbinate bones (conchae) and the paranasal sinuses.
The turbinate bones form into several scrolls of moveable cartilage and bony tissue that is lined with ciliated epithelial cells. The turbinate bones are a veritable maze of structure, and locating a foreign body hidden in their depths can be an extremely frustrating undertaking - a procedure that almost always requires general anaesthesia.
The nose opens to the exterior via two external “nares” or nostrils and the ethmoid bone marks the posterior aspect of the nose.
The paranasal sinuses are extensions of the nasal cavity and various diseases or tumours may impair their drainage (especially of the frontal sinuses). When the dog sniffs, there is forced inspiration and the nostrils are dilated. The inspired air is warmed and humidified as it passes through the turbinates, and the mucus layer that lines the air passages serves as a filter to trap bacteria and particulate matter
