Why Are Some Dogs More Aggressive?

So, what is the reason behind some dogs’ sudden, erratic, aggressive behavior?


And so they say, dogs are the man’s best friend. And like many friendships, the relationship between a man and his dog isn’t without any creases here and there. Unfortunately, when fate rears its head and decides to have it ugly, our beloved dogs turn to biting. And as we all know, canine bites are nasty.

So, what is the reason behind some dogs’ sudden, erratic, aggressive behavior?

According to the latest studies, hormones could explain this behavior.

Evan MacLean, a psychologist and anthropologist from the University of Arizona, states that hormones can lead us to a better understanding of our canine friends’ sudden shifts in behavior.

The culprits may be the hormones oxytocin and vasopressin.

According to the new study posted in the Frontiers in Psychology, dogs are susceptible to these two hormones. To simply put it, these could be the factors that can influence their social behaviors and several forms of aggression.

Oxytocin can be the cause of their temperament while vasopressin can be the cause of their aggression.

Sue Carter, a biologist at the Kinsey Institute at Indiana University, co-authored the study. Carter is an expert in hormonal studies and possesses several decades of research on her belt. Regarding this study, she expressed her fascination about this latest find:

This is the first study that looked at vasopressin and aggression in dogs, and the work opens up novel treatment opportunities.

Furthermore, nature and nurture can also affect a dog’s behavior.

Experts also state that nature and nurture play a vital role in the behavior of dogs. A dog’s childhood experience and its hormones heavily impact its behavioral development toward its adulthood.

Some experts pointed out that testosterone level can also play a major part in a dog’s aggression. However, that doesn’t explain why some dogs are still aggressive even after getting neutered.

MacLean conducted another experiment that involves aggressive and non-aggressive dogs in order to have a deeper understanding of the full influence of vasopressin to the aggressive behavior. The result was practically the same – aggressive dogs have a higher level of vasopressin in their blood. After the experiment, MacLean said:

Before we can work to alter aggression, we need to understand its basic biology. No one had even looked at these other hormones before.

MacLean stated that they are still not 100% sure whether the vasopressin is the main trigger of the dogs’ aggressive behavior, or if it’s just a result of the aggression in the first place.


132-Year Old Lobster Set Free in the Ocean After Living in a Fish Tank for 2 Decades!

His owner finally “pardoned” him and released him back to the water to live out his days as a free man, I mean, crustacean.

You hear about prisoners earning their dues, getting pardoned, and then released from jail after exhibiting good behavior and all that jazz? Well, this was what this ancient lobster must have felt like when, after spending 2 decades in a fish tank, his "owner" finally "pardoned" him and released him back to the water to live out his days as a free man, I mean, crustacean.

Louie the Lobster has been one of the attractions at Peter's Clam Bar on Long Island. A fish tank served as his home for 20 years; he has become such a fixture in there that the owner Butch Yamali considered him more as a pet than the next item on the menu. Butch inherited Louie when he purchased the restaurant years ago - the lobster was part of the package.

Well, Butch loved Louie so much that he refused a customer that offered $1000 to have the lobster cooked for Father's Day.

30 Surprisingly Weird Facts You Probably Didn’t Know About Animals

I’m pretty sure you didn’t learn these in school.

We’ve learned a lot about animals way back our grade school days - from their classes and the way they live to even the hierarchy they're part of. Case in point, we know that doves and chickens come from the same class (birds), though the latter can’t fly. Or the fact that bats communicate with each other using biological sonar. Interesting, right?

While these continue to amaze us, our knowledge about animals is still too shallow. That’s because there is a lot to know about them, and you'll actually be surprised with some of them. Take for example wombats: These creatures actually have cube-shaped poop. Now that’s really interesting. Let's add this: Kiwis - contrary to popular belief - are in fact blind. They simply forage through the use of smell.

But anyway, enough with the tease and let’s get down to brass tacks. Below are some of the most wonderful – and even weirdest – facts about animals. They’re just too strange to believe!

Largest Species of Cobra Found By Researchers In West Africa

The newly discovered species of forest cobra can grow up to 3 meters long which makes it the largest cobra in the world to date.

Somewhere off the coast of West Africa, an extremely venomous species of snake is pretty notorious for pestering the local people because of their invasive nature. Upon investigation, the researchers discovered that these invasive snakes are actually a yet to be discovered species of cobra which is only native to that island.

Initially, the experts thought that it’s just a common invasive forest cobra that got carried from Sao Tome somewhere in the Guinean Gulf. However, further studies unveiled that the native West African snake is actually a new species of cobra.

The morphological and genetic testing revealed that the forest cobra is a new species.
