The hot weather and ozone levels influence dog aggression

A recent study has revealed a fascinating correlation between weather conditions, air pollution, and dog aggression.
The research, conducted by statisticians from Harvard University, analyzed the frequency of dog attacks on humans under varying weather conditions and levels of air pollution across seven states in the US from 2009 to 2018.
The study found that dogs were more likely to attack when the air temperature was high and the concentration of ozone in the air was elevated. Weird.
In total, 69,525 dog attacks on humans were recorded during the observation period, averaging three incidents per day.
The frequency of attacks decreased on weekends and holidays, but increased during the winter months.
The researchers used a Poisson regression model to analyze the data and found that an increase in ozone concentration, ultraviolet index, and air temperature were all associated with an increase in the frequency of dog attacks.
However, the concentration of aerosol particles PM2.5 in the air did not independently influence the behavior of the animals.
While the study does not definitively establish the cause of increased dog aggression under these conditions, the researchers speculate that it could be due to increased oxidative stress caused by the formation of reactive oxygen species.
However, they also note that the relationship between weather and behavior could be more complex, as the reduction in atmospheric pollution in cities during 2020-2023 coincided with an increase in dog attacks on children after movement restrictions were lifted.
The study highlights that dog aggression is influenced not only by weather conditions but also by other factors such as breed and owner experience.
This research adds to our understanding of animal behavior and could potentially help in developing strategies to prevent dog attacks in the future.
This study raises several intriguing questions: What other environmental factors could influence animal behavior?
How might climate change and increasing air pollution levels impact animal behavior in the future?
Finally, Could similar patterns of aggression be observed in other animal species under similar conditions?

I'm pretty sure that in any equal warm species a large increase in ambient temperature leads to higher levels of aggression. There were studies in the 90's on the effects of long hot droughts on the frequency of rampages.... I'll do a search ;-))
When a tipping point is passed, this then turns into total lethargy.
From this point of view, animal husbandry will remain a socially exciting topic.
That's an interesting take. Do we have data about the level of agression in warm countries? Maybe we humans behave like that too.
I'd like to see more.
I'm looking for... However, it might be too easy to do it alone. Southerners, for example, are generally more open-hearted and emotional. Aggression doesn't build up as much as it does here. Nevertheless, an influence cannot be denied, I suspect...
