13 Dog Breeds That Can Become Your Worst Nightmare!

Dogs are often celebrated as loyal companions, but not every breed is as easygoing as they seem. In this eye-opening video, we explore 13 dog breeds that, if not properly trained and socialized, can quickly turn into your worst nightmare! These aren't just dogs with bad reputations—many of these breeds have strong personalities, high energy, or protective instincts that, without the right environment and care, can lead to aggressive or destructive behavior.

We'll dive deep into the factors that make these breeds more challenging than others, whether it's their size, strength, or temperament. From the muscular American Bulldog to the fiercely independent Akita, and from the protective Cane Corso to the misunderstood Pitbull, you'll discover why these dogs need extra attention and responsible ownership to bring out their best.

This video isn’t about fearmongering but about understanding the potential risks and rewards of owning these powerful breeds. With the right training, socialization, and a bit of patience, even these “nightmare” breeds can become your most loyal and loving companions.

Well these breeds of dogs actually require a firm, loving and consistent handling

An owner of Doberman guard dogs told me that they don’t just bite, they tear. They’ll tear your flesh out.

The American Akita is the most serious dog i have ever met, second only to the Kangal that was strangely not mentioned here.

Had a guy tell me his attack dog was totally sweet and it’s all about the owners. But, turned out it had mistakenly bit the guy’s mother….she now has an arm prosthesis.

Doberman is a big baby had one growing up he loved everyone. My Neopolitan Mastiff is more of a guard dog than that Doberman ever was

[juliehackett]

I've had German Shepards but my Neopolitan Mastiff is way more protective than any of my German Shepards ever were. Training was close to the same as I've always trained my own dogs. My Neopolitan Mastiff will never make a list because he's not a popular breed

My Pittie Thor Loves people until they show any type of aggression toward me or my family. Then yes he will attack if given his command. otherwise he gets between the problem and me. He is very gentle with kids, which he really loves to meet. I love pitties and they are very misunderstood. People are the issue not the dogs. Most people should never have a dog because they do not know the breed nor do they know how to care and train them. I have had multipule dogs and breeds over my life of 63 years. I have never had my dogs (pack member) chained outside. This is cruel to them.

Hey, …, If there’s anybody out there that can read this, then I am here to tell you, that I’m not afraid to own ANY of THESE dog breeds, but the small dog that really CAN be my worst nightmare is a Jack Russell. I lived with that small dog for 6 years now, & it’s STILL a threat to me. That is NOT the dog I want, because I am NOT, used to owning a small dog!!! Everybody in the family I live with, didn’t raise my Jack Russell correctly, & now it already IS my worst nightmare!!! They’ve been tricked by my Jack Russell’s gentle appearance, & now I’m always trying to tell them how they are doing everything thing wrong with it, but they say they do NOT, want to listen to anything I say, because they do NOT, want to understand me. A Jack Russell can get bored easily, & they ALWAYS want to let MY Jack Russell be bored enough to let its raging instincts go RAMPART, & now it’s going to be my worst nightmare FOREVER!!!

A Jack Russell’s bark, can be as loud as a landmine that just blew up, & they do NOT, want to do anything with it to let all of its aggression OUT of it, but they STILL hold their love strong for THAT tiny monster. They do NOT know anything about Jack Russells, but I am the ONLY person in my family that knows everything about Jack Russells, & finds that aggressive small dog, the HARDEST to live with. A Jack Russell can run at TURBO speed, & when it’s frenzy mode kicks in outside, they ALWAYS let it run off somewhere VERY FAR AWAY, from the house we live in. And every time they do anything that ends up with having me hearing my Jack Russell snarl, it’s a sign that it will start to bark soon, if they do NOT stop, & its bark can bring a sharp pain to my hearing. And even I do not want to do anything with it, because they all always say that they know all about Jack Russells, but in the wrong way, & I CAN’T stop them from DOING any of that!!!

Every time I watch size, height, & weight comparison videos that have dogs in them, everybody that made them, ALWAYS have their minds FIXED on adding Jack Russells IN to them, & I do NOT WANT that!!! Whenever I see cats that are NOT Maine Coons in my yard, & my Jack Russell starts running up to them, or when I visit at another house, that has TOO MANY common house cats in it, I ALWAYS have to SAVE them from it, because it has a STRONG prey drive, that just won’t stop, a mile wide behind us. And the only cat breeds I want my Jack Russell to run up to, are Maine Coons!!! Every time I hear my Jack Russell’s footstep sounds, they ALWAYS bring back, BAD memories to come!!! And the WORST thing about that small dog, is that a Jack Russell’s bark, always starts with a howl, & hearing THAT kind of a bark from that small dog, is what kept me awake all night, EVERY NIGHT!!!

If I had a PARSON Russell with me instead, then I would have FOUND that small dog okay for me to live with. But whenever my Jack Russell goes anywhere with me, it STOPS me from doing all of the things I want to do. Because my Jack Russell transformed me, from a cute, skinny teenager, to a fat adult, I CAN’T lose weight when it goes anywhere with me, because we’re a LAZY family, & having a Jack Russell with me, made me WANT to gain weight!!! My Jack Russell does NOT, let me end up like Sakura Hibiki when I watched the anime series that is titled How Heavy Are The Dumbbells You Lift?, after SHE lost weight, because when my Jack Russell’s FRENZY mode turns on, its LOUD bark, STOPS me from losing weight!!! And it only lets me stay like Marguerite Farom from the anime series that is titled
The Legendary Hero Is Dead, after SHE gained weight, because when I PUT ON that weight, I do NOT, want to LOSE it!!! And the smallest dog that lets me DO all of that, is a German Pinscher, which is the smallest dog I WANT!!!

And whenever I always watch everybody’s videos for Dogs That Can Defeat Big Dogs & Big Predatory Animals In A Fight, they ALL made me wish I had some giant dog out there, that can save my life from my days of living with Jack Russells, because I feel MUCH safer with owning a giant dog that is used for guarding. And that goes for the giant breeds that are used as livestock guardians too, because I won’t have ANY problems with owning a giant dog. I am NOT, a first-time dog owner, but my Jack Russell is STILL the natural disaster of my family, because they WANTED it to be the dominant alpha of our family. So I am STILL stuck with my Jack Russell that still brings trouble to my family, & I need a giant dog that can put an END to all of this, once & for all!!!

The name of the video should be dogs crappy owners should never this video gives these dog breeds a bad name when in fact its not the breeds fault its the owners. If a Chiwawa was able to cause harm it would be number 1. Uhh I dislike this video a ton.
