Heat , sunlight , and pollution might make some dogs insect bite - happy , new research out Thursday suggests . The work institute that reported heel bites tend to increase on days with high-pitched temperatures as well as day with high ultraviolet or certain befoulment levels . Though more research will be call for to affirm the determination , the author say , other studies have found a similar link between hot weather and hostility in world and other animate being .
The research was led by scientists at Harvard Medical School . They examined publicly usable dog bite data from eight U.S. city , including Los Angeles , Houston , and New York City , from 2009 to 2018 . Then they cut across - reference the data point with daily atmospheric condition and pollution data in those cities .
All in all , there were almost 70,000 recorded dog bites during the sketch point . And the team find a connection between bites and the surround environment . compare to days with lower UV — or low sun exposure — show dog bites go up by 11 % on high ultraviolet light day . They also went up by 4 % on high temperature day , and by 3 % on days with eminent stage of ozone , a common pollutant . Canis familiaris bites slightly minify on 24-hour interval with more rain , and remained unchanged no matter the level of picture to another character of pollution , fine particulate matter , or PM2.5 .

“ We conclude that blackguard , or the fundamental interaction between homo and frank , are more unfriendly on hot , sunny , and smoggy days , indicate that the societal burden of extreme heat and melodic phrase contamination also includes the toll of animal aggressiveness , ” the authors wrote in their paper , publishedThursday in Scientific Reports .
The study does have its restriction . For one , the authors lacked data on other important element that might have influenced the risk of dog morsel , such as breed , sex , whether the dog had been spay or sprayed , or the kinship between the weenie and its dupe . This data point also represents more spartan click bites and not the many mild injuries that go unreported . And of course of study , this character of research ca n’t try a effort - and - burden relationship between dog bites and the environment , only establish a correlation .
That say , plenty of study have found a link between hot weather and increased belligerent behavior in other beast , includinghumans . One common finding , for example , is that violent crime tends to go up during the summer . In humans , this tie-in is potential the resolution of several constituent . Up until a certain point , warm temperatures and fair weather tend to make multitude go out of doors more , for instance , which could then supply added opportunities for difference . But the heat itself might make us crankier and more prone to violence . There have been fewer studies on pollution specifically , but some enquiry has suggested a similar negatively charged effect fromhigher ozone exposure .
As with other animals , it ’s possible that heat and defilement can straight affect cuspid demeanor . But these gene might also change how humans behave around hound in ways that make bite more usual . So the author say that more research has to be done to really validate and interpret this connectedness .
If the link is genuine , then dog bites are poise to become another item on the long list of things that clime change will make bad — right next toworse allergy , more disease - hold ticks , andwildfires .
