Top 10 Worst Dog Breeds

The Top Ten
1 Chihuahua The Chihuahua is the smallest breed of dog and is named for the state of Chihuahua in Mexico. Chihuahuas come in a wide variety of sizes, head shapes, colors, and coat lengths.

Kickable dog, I don't condone kicking a dog but nothing makes me want to kick a dog more than this degenerate rodent. Ratty form and ratty sounds. Gross ass crusty parkinsons riddled rat with no purpose other than trying to take on any dog bigger in size. I would advise a literal rodent as a pet over this thing.

I hate Chihuahuas. They are so ugly and so mean. Even if you are nice to them they decide to bite you, put it down. They are the worst dog breed and are basically a rat.

I work in a shelter and most of the small dogs there are chihuahuas. There are only a couple sweet ones there, the rest are very skittish and mean, and I've seen them go at people for no reason. They bark non-stop and just...aren't smart. They're the hardest dogs for me to handle at the shelter, and I've actually been bitten by several of them. I feel bad for the breed since I guess people get them thinking they're going to be just this little thing that sits in your purse and doesn't do anything, but oh man do these dogs require work. Like any dog, you have to train and properly socialize them, but chihuahuas aren't smart dogs by nature, so they need to be trained when they're real babies. The chihuahuas in shelters are often the result from an owner that did not want anything to do with properly training it, so the dog isn't house trained or friendly. It's sad, but not surprising given that the breed is sort of a "pamper" dog. Regardless, I wouldn't recommend the breed at all unless you have the time to diligently train one as they definitely require a lot of extra time and are infamous for their behavioral issues. Besides, there are much better, cuter dogs out there.

2 American Pit Bull Terrier The American Pit Bull Terrier is a dog breed. It is a medium-sized, solidly-built, short-haired dog whose early ancestors came from the British Isles.

Don't stereotype this dog. I've met one before, and that dog was the sweetest, kindest, most patient dog ever. Yes, some can be mean. But some aren't. To the person who said, " I really recommend people seek a second opinion." You've just had a bad experience. I've had a extremely bad experience with a breed before. I do not hate that breed. You and your neighbor just got the wrong dogs. All breeds have dogs that are bad. What I mean, is that some dogs have bad personalities, some have good. Now, it's fine if you don't like this breed. But I'm just saying, don't stereotype. Thanks for reading, and have a wonderful morning, afternoon, night.

I get that this is a very empathetic way of looking at empirical data, but I guess the logical question is if Pit Bulls are not the most likely to be violent, most likely to kill, strongest jaw and so on then why do dog fighters overwhelmingly choose this breed to fight? This is the dog that is trained to kill and be violent by the the same people that created the breed specifically for that function. I think what people are tired of is the rationalization that Pit Bulls are not going to do what is in their nature with the correct trigger. Hunters hunt, shepherds herd, hounds dig. Etc etc. Maybe mathematically as a percentage of populations the math does not support the stereotype, but to say that Pits are not genetically superior to most dogs for the role of attacking and killing their opponents is patently untrue, supported by the fact that they are mostly used for that specific purpose relative to their World wide populations. Think of it this way.. People tend to have dogs that reflect their own personality. "Not a rule just a norm" Mean bad ass guys select mean dogs. Usually pits or in the pit mix group. Friendly family types select from the lab breeds based on personality and hunters go for hounds. Farmers working dogs. And so on. Cops for instance select shepherds because of their genetic need to work and be active, plus their intelligence. If all dogs were created equal people would not feel the need to have a pet that makes a statement about who they are as well. Overwhelmingly the type of person that has a pit is doing so to make the point that I will attack you and kill you if you mess with me. Same with people that buy dobermans and point their ears. They want you to fear them. My issue is not to kill the breed but for people to stop defending it like they are just like any other dog. They are not. They were bred specifically to fight and kill. That is their genetic legacy and there is no getting around it. They have a predisposition to attack and kill... more

3 Rottweiler The Rottweiler is a breed of domestic dog, regarded as medium-to-large or large.The dogs were known in German as Rottweiler Metzgerhund, meaning Rottweil butchers' dogs, because one of their uses was to herd livestock and pull carts laden with butchered meat to market.

Ahh wannabe dog experts say that they are man but they aren't. Whenever I do a experiment to see what people think about the breed they usually say they are mean, but they aren't. Rotties are usually sweet dogs naturally. The reason for this is because we didn't train our Rottweiler and he still protected the house. The only reason they are banned in some towns is because they are strong enough to kill you but even chihuahuas can be more aggressive. Rottweilers are by far my favorite breed because they are great with kids

Ok the important thing to realize with rotties is that you NEED to train them YOUNG. We've had rottweilers at work who are just the SWEETEST things (one likes to lay her head on my lap to demand pets, and she and her brother and baby faced little angels who would cuddle you for hours and I love them), but when we do get an aggressive one, it's incredibly dangerous because they're so BIG. And no, it's not about them growing up in a crappy environment, it's just about socialization and training. We have one regular, Rocco, who we've all known since he was a puppy. The owner is nice, but an idiot, and didn't train him as a puppy. Now, Rocco is 3 years old and can be sweet sometimes, but then snarling and aggressive at completely random moments, and he is the most dog aggressive dog we've ever had. He has to be walked with a muzzle on and with a can of dog pepper spray in hand, just in case. The owner is TRYING to train him now, but it's hard to train rottweilers once they're older.

If you're going to get such a huge and muscular dog who is capable of causing a lot of damage, it is your RESPONSIBILITY to train them effectively. If you don't have the know how, and aren't a commanding person they will listen to, DON'T get this dog, because you're doing the dog a disservice, and you're putting people and dogs around you at risk. This is true of any large, muscular dog breed. Be a responsible owner, or find that dog a better home. Because if they ever hurt someone, it'll be your fault.

4 Chow Chow The Chow Chow is a dog breed originally from northern China, where it is referred to as Songshi Quan, which means "puffy-lion dog".

At work, chows are some of the meanest dogs we get. They're even worse over in grooming, where basically all the groomers say they're universally dreaded. We just had a chow in last weekend who had to wear a muzzle, and it still took 3 groomers to groom it. They can be VERY cute, but just incredibly aggressive and awful, and for some reason people rarely bother to train them (or maybe they just don't successfully train them). I think we've had like ONE good chow, and she lived in a house with a small dog and was clearly well trained and socialized.

These things are monsters they might have a cute fluffy friendly look but still. My friend has a chow named William he bit me and it broke my skin it was pouring blood he also has bad house manners and he hates my dog Holly a sweet little husky. And my friends parents have him away thank god and then they got this cute little boxer and he is so sweet his name is Chewy.

5 Presa Canario The Perro de Presa Canario, A.K.A. the Canary Mastiff, is a large Molosser-type dog breed originally bred for working livestock.

We have a couple canary mastiffs who stay with us - one is a sweetheart who will let you literally nap on her, and the other is so aggressive that none of us will go near it without a large male tech helping us. they have the same owner too, so I don't think it comes down to only training, I think it's partly just personality too.

These Dogs are amazing I don't understand how some people hate them. I understand that these dogs can some times be rude but it's because how there trained train them right and these dogs are amazing also there very loyal.

I get it people are scared of it but that doesn't mean we have to put down all these dogs that are living. What is people came to your house and said you're gonna die come with me. It's not fair for the dog

6 Doberman The Doberman Pinscher, or Dobermann, or Doberman, is a medium-large breed of domestic dog originally developed around 1890 by Karl Friedrich Louis Dobermann, a tax collector from Germany.

The used to be bad but most of the aggressiveness has been bred out of most lines. The modern Doberman is rather docile, loyal, intelligent and very trainable. A couple of walks a day is more than enough to keep the energy of most individuals down and steady and I'd even go as far as saying they're acceptable apartment dogs. No reason to be on this list to be honest. Smart, loyal, loveable, very few breed related negatives that I could think of.

We have had four wonderful Dobermans--Missy who was to be put to sleep because her owners did not want her--gave us 10 wonderful years--Loni--a breeders special dog. She gave us another 10 wonderful years--had to have a Malignant tumor in her eye removed. Allie who developed liver cancer at age four. And now we have Leisel--a throw away from Doberman rescue in Lake Placid Fl. She had been running the streets as a feral dog. She has been difficult--we gave her back twice! But realized she needed a family. She is 3/12 so we have a long way to go!

7 Alaskan Malamute The Alaskan Malamute is a large breed of domestic dog originally bred for hauling heavy freight because of their strength and endurance, and later a sled dog.

I have two Malamutes both females and they are well behaved girls. I don't know where you came up with the impression that they are a bad dog. Yes they are stubborn and get into things like every other dog I have had. I have 6 grandchildren and the dogs are right there with them and guess what NO ISSUES. They wait patiently for the kids to drop their food cause they are foodies. I appreciate that some people have had bad experiences but if you treat them like family they become family. If you abuse them you get what you give in return.

I live on base housing, where 90% of everyone owns a German Shepard, malamute, or husky. I haven't meta single person yet(with a few exceptions for the German shepards) that haven't regretted getting these dog breeds. Malamutes and huskies are not good house pets. Haven't a big yard isn't the answer either. You need to have a profession that involves spending time with them, and working them hard in order to get them to behave some what docile.

8 Dalmatian The Dalmatian is a breed of large dog, noted for its unique black or liver spotted coat and mainly used as a carriage dog in its early days.

Completely retarded, does NOT listen, stubborn, neurotic, can not be voice controlled, incapable of learning any tricks, never comes when called (in fact runs the opposite direction), purposefully runs from you when it's time to go inside (thinks everything is a game of chase me), not food driven (could care less if you were offering it a treat to be good, more interested in being bad). The goal of this dog is to frustrate its owner as much as possible. I can't say enough bad things about this breed. I will never get a Dalmatian again.

My next door neighbor had Dalmatians for years and they were always horrible. They run EVERYWHERE including away requiring animal control to find them. I eventually thought it was poor training from the owner until I came across them later in life and noticed the same poor traits. At this point, it must be the breed.

I have had three dalmatians attack me and my little jack Russell terrier. I never had a good experience with a dalmatian yet.

9 Afghan Hound The Afghan Hound is a hound that is distinguished by its thick, fine, silky coat and its tail with a ring curl at the end.

Who ever put this here is stupid, I have one at home called Silky and she is the best dog! When my family members came to celebrate a festival or event they will bring my cousin's friends's little sister. When we let Silky came, she just ran over to the little girl, and starting playing with her and licking her on the face! When she got sick, she didn't even bother about her sickness! We were going on a vacation, and she went to see us leave, and each gave us a lick, and a rub on your legs, we love her. So you guys better change your minds about them! I love her, and I will forever. Don't judge a dog by it's looks, who ever thinks they're creepy and scaring, it's natural so better deal with it!

Don't be stupid I have a grandma that has 1 and she's a great dog sometimes she will bark at the door but that's it. She loves children, people, and even my grandma's other dog Max. Which is the only dog she's ever known except for 1 that died. I never want to see this Afghan Hound on the top ten list ever again. I'm definitely using another website.

10 German Shepherd The German Shepherd is a breed of medium to large-sized working dog that originated in Germany. The breed's officially recognized name is German Shepherd Dog in the English language. The breed is known as the Alsatian in Britain and Ireland.

I think this is one of those dogs that can be absolutely WONDERFUL as long as you train them properly. Don't get one without doing your research, and being able and willing to train them. But I work at a pet resort, and we don't tend to have a ton of issues with German Shepherds. Some can be dog aggressive if they haven't been properly socialized, but I think the main thing to look out for with them, that I don't see brought up a lot, is anxiety. A LOT of the German Shepherds we get have really bad separation anxiety, and end up destroying things in rooms or crying constantly, or having to wear a cone because they won't stop chewing on their tail. They're generally very sweet though and unsurprisingly can be GREAT guard and companion dogs when properly trained.

The German Shepherds entry should be REMOVED from this list! German Shepherds are the kindest, most loving, obedient, intelligent and loyal dogs of all time. I've been blessed to own 2 of them and there was nothing aggressive about them whatsoever. Far from it and they were great around children. Sure they can be trained to be aggressive ON COMMAND which is the reason they're used for police work, and at the same time, they make wonderful gentle pets. Show your German Shepherd dog the love & the respect they deserve and they will repay with their love and devotion always.

The Contenders
11 Shih Tzu A shih tzu also known as the Chrysanthemum Dog, is a toy dog breed, weighing 10 - 12 pounds when full grown, with long silky hair.

They are a bit ugly and noisy, but mostly from what I've seen they have an OK personality. They are nowhere near as awful as Chihuahuas.

I don't hate them, but their temperaments seem to be very unpredictable. Some are very friendly and calm, while others are very irritable and snappy. It's hard to believe that they're from the same family of dogs (Chinese toy breeds) as pugs, since I've never met an unpleasant pug, but Shih Tzus are sometimes very "mean and nasty", like my grandma's dog.

Can't stand them. Almost all the shih tzus we get at work are aggressive biters, who are never trained because people for some reason think they don't need to train small dogs, and who never shut up for a single second. I'm sure if you trained the dog, they could be good. Honestly most of the time, a bad dog just means they have a lazy owner.

12 Boxer The Boxer is a medium-sized, short-haired breed of dog, developed in Germany. The coat is smooth and tight-fitting; colours are fawn, mahogany, black or brindled, with or without white markings, and white.

I actually hate the way this thing looks, imagine taking what would be a decent looking dog and then slamming it's face against the concrete a few hundred times. That's this dog

My Boxer is the sweetest dog ever. She loves people and has a strong desire to lick everyone she meets. She has a raw intelligence that for me is unusual. Whthout training I can tell her to go into the other room and she know what to do. Sit, lay no problem. Great with my 6 year old daughter. I cannot say enough good things about this sweetheart.

I understand why their on this list because of their energy but they aren't bad dogs! My next door neighbour had a boxer fully grown 1 and he is so cute and playful. I was taking my tiny lol shih tzu/ something for a walk today and the boxer was so excited to see my dog. He was like, so funny with what he was doing, hard to explain... I'm sorry but this list is disappointing. Most of there dogs are really nice.

13 Komondor

Yes, I agree with the person who said this list is VERY stupid.

To be honest I really don't like the look of these dogs...

Unique dogs. Cool dogs also.

14 Spanish Mastiff
15 American Bulldog The American Bulldog is a breed of utility dog. There are two specific types of American Bulldog, Standard and Classic; additionally, there are also hybrids of the two types.

I imagine this thing being in a nightmare chasing you down, this is the type of dog people say "he won't bite" but then the thing chomps your fingers.

I don't agree. It's a lot like the pug. They are hated for no reason. They have health issues, due to massive breeding. I love them, and pugs as well. All dogs are cute. This dog shouldn't be on here. It's too sweet! They are so kind and are only the way they are, because of mass breeding and such. Shelters and such are the way to go. Don't go hating on them because of their looks, hate the people that made them look like that! It's not the dogs fault

Along with the pug, these are one of the best dogs ever!

16 Poodle The poodle is a group of formal dog breeds, the Standard Poodle, Miniature Poodle and Toy Poodle. The Fédération Cynologique Internationale recognizes four sizes of one breed: standard, medium, miniature, and toy.

Poodles are my most hated dog by far. They are aggressive, high strung, have the attention span of a gnat, have an extremely loud, bassy, high pitched bark, and they look absolutely ridiculous. However, I don't know what's worse, poodles or their owners, who sit idly by while their dogs attack and bit other people and other dogs.

I have a phobia of poodles. They're so mean and bite. I have childhood trauma thanks to Poodles. I remember being like 4 or 5 and my Aunt's poodle would scare me and I'd be afraid to get off the couch. Til this Day, whenever I go bike riding, poodles in the neighbor hood would chase me while I'm riding my bike. I pedal as fast as I can to get out of there. I look back and see them chasing me, and trying to bite my feet while I'm pedaling. Super scary. They also bark so much. I get panic attacks when I see pictures of poodles, and it's not just poodles either. Maltese scare me as well as Yorkies. They all have similar characteristics. I'm still trying to heal and resolve my childhood trauma.

17 Fila Brasileiro The Fila Brasileiro also known as the Brazilian Mastiff is a large working breed of dog developed in Brazil.

Hello people. I am of Brazil and know a lot about dogs, surprising lots of adults for being of small age. They are not fat. Anyways, the dog in the photo is not the real size of Fila Brasileiro. For me, they are the best, because if some stranger wants to hurt me, he would hurt that man. Has 24/7 of the protection level, does not need too much care with fur, loves its owner, full of courage and bravery. Now, Americans, please, you beat us in lot of stuff. Richest country of the world, language is more talked than ours, bigger territory than ours. Now let us have a turn to make something good because looking to USA Brazilians are like poo.

It. looks pretty big and mean but don't judge it by it's looks it can't help that

This dog looks fat

18 Pug The Pug is a breed of dog with a wrinkly, short-muzzled face and curled tail. The breed has a fine, glossy coat that comes in a variety of colours, most often fawn or black, and a compact square body with well-developed muscles. However, Pugs have difficulty breathing, due to their extreme head shape.

A really cute dog breed and they mostly have a very good temperament. I like these dogs a lot. Sadly it's also a showcase of why humans should stop breeding dogs out of frivolous cosmetic reasons.

As much as I like the breed, they shouldn't be bred. And people should stop buying them.

I read most of the comments ( negative ones of course ) and I came to a conclusions. I own a pug too and I don't think it is animal cruelty whatsoever. You can't really shape the way your dog will come out, plus, everyone has preferences and came here to justify themselves. My pug is not disturbing me and my studies, since I am mostly busy with school projects. I come home and play with him and train him. The first time I tried to train him into food waiting he got 10 tries then he was good. One week later, he was mastering it. Yes, it has major health problems, but it depends on the owner too. The owner has to take good care of its conditions as they can be avoided ( never say it is impossible ) with hygiene and cooling it down. So, if you want to get a pug, accept that you are going to need good conditions before you get one.

19 Bull Terrier The Bull Terrier is a breed of dog in the terrier family. There is also a miniature version of this breed which is officially known as the Miniature Bull Terrier.

HOW this dog is so sweet and is so cute! It was probably put on the list because people think there ugly. I want one and would name (if a boy) it Severus because of the sorta hooked nose.

I feel bad for this dog because people actually think it's ugly. It looks pretty funny and cute for me.

I agree with people saying these are funny, but this is not cute. Sharkheaded ass elongated face tiny eyed mess of a dog.

20 Miniature Schnauzer The Miniature Schnauzer is a breed of small dog of the Schnauzer type that originated in Germany in the mid-to-late 19th century.

These people aren't lying. It should be law that these things come with a "Buyer beware" sign around their necks. Listen when people say these things stink. You must bathe every week... Catch 22 here is that if you give them a bath more than once every two or three weeks their skin dries out and they start to scratch and lick themselves... their hair doesn't dry either so before you know it, you got a smelly wet with slobber dog that needs a bath again. Good luck

These dogs are ugly as sin and are one of the most high maintenance breeds. They also stink to high heaven. My friends wife got one as a puppy because she thought it was cute then... Big mistake. They literally cannot find anyone who will take it off their hands. Unless you have lots of spare time and money to burn on one of these ugly rats don't get one.

Violent with other animals, children, strangers. Won't listen, hard to house train and backtracks often even with professional trainer, destroys everything, never stops howling and barking at everything and everyone and thus far it's 8 months old. Avoid.

21 Dachshund The Dachshund is a short-legged, long-bodied, hound-type dog breed with floppy ears, and short fur. Although, this Dog, which comes in a variety of colours, is not hypoallergenic.

Cute looking dogs and good temperament. Usually the owner is the bigger problem than the dog. Some owners of these breed are absolute morons who should never own an animal. And no putting a hot dog bun outfit on them isn't funny or original.

Have a dachshund myself, and they can be sweet and they can be crazy mean. They are terrible with other people if they weren't raised being around much others. And don't even think about letting little children near them. They are very sweet to you if you are sweet to them, but they will bite anyone who walks through your door. If you are wanting a dachshund as a pet, but have never had a dog before, I would not recommend this breed.

Dachshunds are cute dogs who are loving and very true to owners and loyal but can be very yappy-barks a lot. I have 2 dachshunds named Bart and Bixel. Bart is 15 and will be 16 in February. He is calm and laid back but loving and affectionate. The doctor said he could live until 20. He is my best friend forever. Bixel is 7 years old and will be 8 on July 6 (5 more days). Bixel is funny and loves to cuddle and kiss people. He can growl at other people but only if he feels I will be harmed. He is the most loyal and smart dog ever. I love Bart a little more though. Go hot-dogs! (Dachshunds)

22 Yorkshire Terrier The Yorkshire Terrier is a small dog breed of terrier type, developed during the 19th century in Yorkshire, England, to catch rats in clothing mills.

Everybody has their different opinions on yorkshire terriers but I got to say, yorkshires are probably my least favorite dog breed. A couple months ago when a friend of mine hosted a halloween party, they allowed me to feed their yorkshire, Lola. It was going fine until she suddenly snapped at me and started growling, I could have lost a finger from that experience! Plus I didn't even do anything to deserve that. For those of you who are thinking of buying a yorkshire terrier, I'm warning you that usually art good with kids.

GOD these dogs are annoying as hell. We have a lot stay with us at work, and they're pretty much always dumb as rocks, and they tend to pee all over the floor constantly and they never SHUT UP and they have the most annoying high pitched yap, and a lot of them tend to bite. They're a spoiled, pampered breed with almost no redeeming qualities beyond their looks (if they are what you consider cute). I can't stand them.

23 English Bulldog

Anybody who supports the continued breeding of bulldogs is either completely uninformed, or just awful. We've messed up this poor breed so badly, it shouldn't exist as a purebred anymore. If you MUST get a bulldog, get a mixed one from a breeder who's trying to introduce new blood into this incredibly inbred breed. Nobody should even be ALLOWED to continue breeding pure English bulldogs, it should be considered animal cruelty at this point. When you've bred a dog to the point where they're so disfigured that the mothers can't even give birth on their own anymore, and where they have so. many. health issues, it's inexcusable to continue trying to keep them "pure". Disgusting, what we've done to them.

I feel like this should be higher on the list. Bulldogs shouldn't even exist. They can't give birth on their own, and have many health problems. But some disgusting human beings decided "Yeah let's make this thing exist" but that was wrong. It should be considered abuse for them to exist because their lives are terrible.

24 Akita

My akita is extremely friendly with children, but she hates most black people and mexicans. She also just acts like a giant stubborn toddler, she refuses to move off of the neighbor's lawn when their dog is out. I'm surprised that this is 30 on the list, they are stubborn, annoying, and extremely jealous around other dogs. Akitas are sweet and cute though...

Mine has chased away many a spook and mexican best dog I ever had.

25 Basenji The Basenji is a breed of hunting dog. It was bred from stock that originated in central Africa. Most of the major kennel clubs in the English-speaking world place the breed in the Hound Group—more specifically, in the sighthound type.

Yep, probably the worst breed we've ever had. A neighbour bred them and gave us one as a gift. The parents were both aggressive little dogs that hated other dogs.
The puppy they gave us at about 12 weeks old (pretty much straight after getting him),
latched on to my little sisters bottom lip when she petted his stomach and must've woken him. The bite even from a puppy was quite bad and required stitches.
My parents quickly gave the dog back to the neighbours.
We've had Rottweilers, German Shepards, Blue cattle dogs & even bitsa's that we're from pig hunting dog litters & none of these breeds was as aggressive as the Basenji's we seen.

This is an African hunting dog and isn't good with people.

Total Spawn of Satan. Yeah they don't bark, however these loner dogs whine like no other. They are high strung and not at all for children. We had two throughout my Childhood and they both were aggressive, and would growl at us.
