It drives dog proprietor nut . You ’re out for a pleasant perambulation with your dogtooth companion , and because some asshat did n’t pick up after their own pooch , a refreshful , muggy turd is sitting right there on the pavement . Before you have fourth dimension to oppose , you horrifyingly ascertain your presuppose best admirer pounce upon the poop , gobble it down in the blink of an eye .
But why ? Seriously , why ?
What could mayhap oblige a frump to eat another dog ’s poop , or in some cases , its own crap ? It ’s a baffling behaviour , because dogs run to be antipathetic to the stinky stuff , not shitting in their own beds , so to speak . In a Bible , it ’s a self-contradictory behavior . Many dog owners are understandably implicated when their ducky do this , fearing that something ’s psychologically incorrect with their dogs , or that the poop might make them sickish . And no one wants to be licked by a dog who just pounded down a steaming pile of crap .
But it ’s not just dog owners — scientists are also funny and implicated about this strange behaviour . In an exertion to learn how common shit - eating is among bounder , and to count on out why they do it , a team led by Benjamin Hart from the University of California at Davis got thousands of dog owners to nail a brace of vane - based surveys .
The first survey , involving 1,552 andiron owners , assess the frequency of this behavior in bounder , while exploring potential differences among turd - eater and non - poop - eaters . The 2d view , with its 1,475 respondents , explored the reason behind the behavior , and to determine if commercial-grade treatment intersection actually terminate blackguard from eat on their own poop ( spoiler alert : they do n’t ) . firedog are known to eat turd from other coinage , but this study focus entirely on the phenomenon of “ coprophagy”—the act of repeatedly eating one ’s own poop , or the skinny from members of the same coinage .
resultant role show that 16 percent of frankfurter are coprophagic , meaning they have eaten after part on at least six dissimilar occasions , as keep by their owners . And dogs who eat dope tend to do it often : 62 percent ate stools daily ( whoa ) , and 38 percent weekly . But the dogs were finicky . The vast legal age of the poop was fresh , no more than two days older . Any older than that , and the dogs incline to avoid it . Theseresultswere bring out last week in the skill journal Veterinary Medicine and Science .
Looking at the information , the researcher clamber to find connections that could explain the deportment . old possibility have suggested stress and anxiousness , or dietary insufficiency , but the young results do n’t entirely support these ideas . For example , no link could be found between a pawl ’s age , dieting , strain , neuter status , or the age at which it was disunite from its female parent . Poo - eater were just as easily menage trained as those who deflect the habit , “ suggesting a normal aversion to feces , ” write the authors . The behavior was more vulgar in multi - dog households , but that ’s in all probability because there ’s more entree to shit .
But the researcher did manage to obtain one possible causal ingredient : proprietor with nincompoop - eating bounder run to describe their cuspid companions as “ avid eaters , ” compared to non - coprophagic dogs . More on this in just a second .
As for the success rate of commercial-grade discourse options ( typically food additives and oral contraceptive pill that are hypothecate to make dogs averse to their poop ) , the researchers enunciate their effects are “ close to zero , indicating the behaviour is not readily changed . ” So do n’t pine away your money , or potentially compromise your dog ’s health , with these products .
As to why dogs do it , the researchers say it may have something to do with their unwillingness to eat poop older than two days .
As already observe , coprophagy is a self-contradictory behavior for detent . They ’re naturally averse to the stuff , and they avoid pooping where they live . This antipathy is probably inherit from their angry wolf ancestors , who evolved the deportment to avoid fecal - borne intestinal parasites and other pathogen . Well , it just so befall that the eggs of parasites do n’t typically hatch into infective larva for a few days . concord to the new theory , the eating of bracing dirt among ancient wolves may have been a way for them to “ clean up ” when a sick , old , or lame wolf accidentally or unwillingly plump some poop in its own hideout . Thus , poop - feeding is an adaptative demeanor that helped canine ascendant avoid intestinal parasites .
James Serpell , a prof at the University of Pennsylvania ’s veterinary school , toldthe Washington Post that the theory is “ plausible , ” but that the “ greedy eaters ” observance advise dietary motivations . Studies done elsewhere have shown that loose - stray dogs in uprise rural area eat a pile of human feces to make up for dietetic lack . What ’s more , today ’s dogs and hombre “ are feed diet that are relatively plenteous in fats and protein , not all of which may be completely digested , making their feces potentially attractive as a second hand intellectual nourishment source , ” Serpell told the Washington Post .
The newfangled theory is interesting , but not completely satisfying . Coprophagy is a very hard issue to study , and there are many plausible reason why cad pander in this behavior — from wanting to grab a quick meal or out of vapourous tedium . And in fact , the reasons may diverge from dog to click , and move by an salmagundi of known and obscure ingredient . It ’s also crucial to charge out that this study was drive by ego - reported surveys ; the scientists had to swear on the assessments of dog owners , and describe such subjective traits as “ avid ” feeding .
While an answer to this question is still coming , it does appear that low-down - eating is something that dog normally do . That does n’t mean you have to like it , nor does it entail this it ’s a completely healthy behavior for dogs ( in some cases , it can induce diarrhea , and even the transmittance of parasite and disease ) . More often than not , a wiener will be okay after chomping down on a deuce , but interested owner should work their dog-iron to a vet in face they ’re apprehensive . As for prevent your andiron from exhaust poop , your serious bet is to keep your backyard poop - gratuitous , and keep you dog on a deuce-ace while out for a base on balls .
