Despite their strongsense of smell , detection dogs that have been trained to keep track of other animal ’s scents in conservation sites still make mistake . The fault happen four to 45 percent of the time , where the dogs end up locating the untimely targets .
ordinarily , dog handlers ascribe the mistakes to errors during the cuspid training . Butthis new studyfrom Washington University confirmed that there might be three potential variables beyond the common sensing .
“ While the reasonableness underlying coprophagy in domestic dogs are still foggy , it is known in tempestuous canids that coprophagy is lifelike and is often associated with territoriality or nutritionary benefits . So while the determination that coyote will consume puma scat singing is novel and has various bionomical implication , coprophagy occurs naturally under a variety of circumstances . ”

How Detection Dogs Work in Conservation Sites
catching dogs utilise their sense of smelling , and not their sense of sight , to feel specific targets , such as scat singing or droppings , that indicate whether there are other fauna in the orbit . preservation sites employ the catching dogs in office of other alternate mean value , such as a camera photo cakehole and other incursive equipment , to identify the comportment of endangered creature .
The dogs are deemed effective because they can smell out brute poop that has been fragmented on the terra firma , or hidden behind bushes , or rained on , or eaten by other animals . But while finding the ill-timed scat do n’t always mess up with the organization , testing the dung that rick out to be fictive positive cost fourth dimension and resources .
Part of biologist Karen DeMatteo ’s work is to traverse endangered puma and other secluded animals in conservation sites in Argentina . She has worked with a number of scat - spotting firedog and trainers to know how often the fault go on .

DeMatteo say in the press release that the mistakes could n’t be always assign to the andiron ' training . The conservation internet site has such a complex ecosystem that it ’s possible some direct scats could be alter .
When Animals Eat Other Animals' Poop
The scientist say that a potential grounds for the inaccuracy could be becausecoprophagy , or the feeding of feces , is common and instinctive to beast . domesticize dogs , and even Arabian tea , also demo this behavior , which human being find appalling .
However , in the wild , eat another animal ’s poop has some nutritional benefits . It ’s also affiliate with a defense of its territory . It ’s not unusual in preservation sites to find puma droppings contaminated by prairie wolf that have tried to exhaust it , thus altering the type of scat singing that the detective work dog might determine .
Sometimes , point scat might also have weewee mark from other animate being . As other animals also pick up the droppings with their rima oris , then the scat can be contaminated with their saliva . These naturally occurring incident also impact theability of the detecting dogsto accurately identify and settle their quarry .
The Study’s Implications
In the U.S. detection dog training has been growing in numbers for the last two decade , specially as there ’s an increasing requirement for their kind of body of work in preservation projects being guarantee all over the world . Most of these detection bounder are really saving dog . handler spend at least 13 weeks for a dog to learn the scents of 12 dissimilar mintage .
These dogs , however , are not trained to chase after the wildlife . But their purpose of saving the wildlife often resurrect questions on the monetary standard of training .
DeMatteo stressed that while sensing pawl preparation is still the gravid factor to inaccurate detection , the variables she has key must not be ignore when taking in generic test results of scat singing samples . The study foreground , therefore , the motive to eliminate such polluted sample when doing familial test , as it might impact how preservation workers discover parasites or diseases or see the worldwide health and well - being of in the endangered brute .
