Top 20 Most Aggressive Small Dog Breeds in the World

MT

Breeds like pit bulls and rottweilers get a lot of attention as being “aggressive” breeds. In contrast, most people think of small and toy breeds as cute, clownish and harmless, but that is not always true.

Some small breeds have been bred to hunt and kill prey, and others can be aggressive due to fear or inbreeding, and you should take that possibility into account when choosing the right dog for you.

Here is a look at some of the most aggressive small dog breeds.

1. Manchester Terrier

The Manchester Terrier is a bright, lively and energetic breed that is usually good with kids. These dogs are very playful and enjoy plenty of exercise.

However, like most terriers, the Manchester was bred to hunt vermin, and it was very good at that job thanks to its tenacious and sometimes even aggressive nature.

This terrier has a strong prey drive, which can lead him to be aggressive with smaller animals. He is likely to take off and chase birds, squirrels and other outdoor critters, so keep him leashed outdoors.

The Manchester terrier is not a good choice in a home with small pets like kittens, hamsters and guinea pigs. These pets will not be safe around a dog that was bred to hunt them out and kill them.

The Manchester Terrier is generally not a threat to humans if it is well trained. However, these dogs do need their own space, and can snap at people who refuse to leave them alone when they want some alone time.

As a result, they are not generally recommended for families with very young children. Older kids who can understand when the dog wants to be left alone should not have a problem, however.

They are so cute. My best friend had three miniature dachshunds. And at one time or another, I have been bitten by all three. Once, I stepped over one of the dogs and she jumped up andnipped me on the inside of my leg. Once, the dog bit my shoe and held on and I tried to shake her off. And once I walked in the house and got bit on the foot. They never bit my friend or her family tho, of course.

Then you got very lucky indeed. I used to work at a vet clinic and ALL of the Lhasa’s were A-holes! Aggressive from the beginning before the exam even started, and always snippy and trying to bite us. They even nipped at our heels when we were just letting them out of their kennels to use the bathroom.

In 2000, I took to foster a 2 yr old puppy mill Shih Tzu from a rescue group. (He was big, I thought, for a Shih Tzu.) It took 3 adults to put a harness on him and he bit me twice in the process (tiny teeth so not so bad). For the next several months we couldn’t get near him but, as I was not working, I had plenty of time and patience. By18 months he was comfortable with strangers, us 3 not so much (transference?). By the following year he was a “normal” dog. He wasn’t adopted out… Read more »

We rescued a 1 year old Shih Tzu and have had him for 3 years now. He growls when touched, bites both my husband and me. I am at wit’s end as to what to do. We love him but don’t like him very much. Can’t afford obedience school or training and we are definitely good dog parents. Have been around dogs all my life and am totally baffled by his behavior. Had a wonderful Lhasa Apso from a puppy until 15 years old, sweetest dog ever, female.

try some boiled liver treats for good behavior – that helped with a friend’s dog who snapped at people – worked like a charm – reward good behavior and into the ‘time-out’ corner for the bad behavior. Guess your Shih Tzu’s abuser was male don’t you think so??

He sounds like he is me when I was around twelve. Have you thought that he might have a tumor, or a compromised nerve? Nerves can cause all kinds of bad consequences.

We had a Lhasa Beagle mix, he was my wife’s dog pure and simple. He would have given his life to protect her. What was interesting was the first time I put a leash on him he was all business, fell into a heel, looking straight ahead, end of discussion. But If the wife and I started playing around, I got a mouth full of teeth. Anybody new to the house, they got bit, after that it was fine. Another funny thing was he loved to chase a tennis ball, in the hall, it’d bounce like crazy and he’d get… Read more »

Totally disagree that Lhasas are one of the ‘most aggressive small breeds.’ Our Lhasa (named Sasha) has been with us for 8 years (she’s 10 now) and I have yet to see her be standoffish with strangers or nippy. This dog lays around 85% of the time and loves human attention. She will bark to let us know when someone is approaching the house, but once we open the door, her guard dog duties end and she wants to be petted by our visitors, lol. We also have a 5 year old daughter and my dog and my kid have… Read more »

Almost all dogs were bred for a purpose – if they were bred to flush game (Cockers), they bark. If they were bred to ride horses in the hunt, they jump (Jack Russells), If they were bred to guard, they get their hackles up in a hurry. The mistake is not researching the dog’s origins before getting one.

BlueVibe
Guest

That’s one Lhasa out of how many?

I grew up with American Eskimo dogs. My last one was almost silent–she could bark, but rarely did. Nevertheless, the breed as a whole is very vocal and I would never tell someone, “Well, people say they bark but mine didn’t so I don’t believe it.” They bark. Oh, how they bark.

Traits are not universal, but that doesn’t mean that they aren’t present in the majority of a breed.

Oh, man. As a groomer, the worst and most vicious bites I’ve gotten were from two different Eskimos. I’ve groomed some very nice ones, some loud, some quiet, but when they bite, they do it instantly and without hesitation.

here is another Lhasa….He passed at 18 years and never once growled or nipped or bit anyone. Friends argued as to whose turn it was to watch while I was out of town. From the beginning, do not allow your dog to be aggressive in any form. Kids showed up at door to play with him (parents approval) Train you pets with love and kindness and you will have a loving pet in return.

So true, the Weimeraner (few people know the true spelling, which this isn’t) I had was a stud that never was aggressive when it came to other dogs, unless one came at him.Then he was a true warrior and kicked butt. He was an outgoing goof with people, and ignored other dogs. They weren’t interesting to him. He did jump on a random walker woman going past my front yard once, but he was just jumping on her chest to say hi. Poor old gal freaked, and Lucas was in lockdown for ten days.

I grew up with Lhasas since I was a baby. My family has always had them, and I soon plan to get one of my own. It really bothers me when I see one or two pointed out as aggressive. This is almost always the fault of the owner but can sometimes be pinned down to puppy mill breeding. My mother has never had an aggressive Lhasa. Stubborn as they may be, they can easily respect you as an alpha, and that’s all you need to do to avoid “small dog syndrome” with them. However, they might bite a criminal… Read more »

most breeds were created with a task in mind – killing rats, protecting the castle, sitting on laps. (only dogs with these traits were used for breeding) I now have a yorki who chews everything, has boundless energy – perhaps the original task was lapdog and entertainment. He’s been the same since he was 8 weeks old.(18 months now) He’s gone to dog school, but if i’m not looking at him asking for attention – he’s happily destroying anything small. I have a peke that came here shy at 10 weeks, she’s the house boss but still shy, tail down… Read more »

If you substitute “protective” rather “aggressive,” it’s clear that genetics as well as training/socialization does play a part. There is a reason that the military, police, security workers & schutzhund fans (and thug types 🙁 ) gravitate to certain breeds — German shepherds, Dobermans, Rottweilers, the Belgian shepherd breeds, among others. Those breeds are not inherently vicious , but it is easier (whether with proper training, or with poor training and poor socialization) to elicit “aggressive” behavior in those breeds than in most breeds. Collies, greyhounds, English and Irish setters, golden and Labrador and flat-coated retrievers (among others) are all… Read more »

What Peggy Tibbetts was saying is that it’s not about dog breeds (because no dog was bred for the purpose of turning on their owner), it’s about the dog as an individual. Just like you see a lot of bite statistics for labs because of their popularity, you see statistics with the breeds listed above for their popularity. The only difference being that there are many more ignorant fools wanting to own an “aggressive” Pit Bull or Rottweiler to look tough/cool than there are people wanting to flaunt a lab for the same reason.

They choose the dog’s because they are easy to train, and have a good “ball drive” it has nothing to do with their love for attacking people. Military work dogs are not vicious.

You’re wrong.

Some breeds have been bred for hundreds of generations for certain types of aggressive behavior and they are basically hard-wired in that regard. No amount of training and hoofing it up and down the street will change what is in their DNA and breeds of that sort should never be trusted 100%.

Apologists for these breeds/types will tell you it is the owner, not the dog – but it is the dog. The genetics of the situation sets the stage and all it takes is the wrong set of circumstances and the dog will attack.

So I shouldn’t own a GSP if I have a child because it will hunt it? It’s about being responsible and training your dog responsibly. It’s funny that you use breeding and genetics as an argument, when these dogs that were bred for “aggression” were bred to listen to and protect their owners under any circumstances.

Not entirely. Some breeds have been bred to be overly aggressive. I have some friends that had Pit Bulls, and every single one of them turned very aggressive after they were – oh, maybe 5 years old or so. He treated them very kindly and affectionately too – I was around to see several of them change. They became so aggressive with kids in general that they had to be removed from the house.

I had a neighbor with an annoying, yapping, min pin that did it’s best to act like he’d claw your heart out. The neighbor was a great guy, and I saw no neglect of this dog, or mistreatment.
It was the most irritating punk dog I’ve had the misfortunate to live near to me.
But, at the same time, I had a friend that owned one, and it was a cool little dude. And yes, pertaining to people, there’s an asshole born every minute, as well as a sweetheart.

I agree with Peggy. Exercise your dogs people. I have neighbors that to me are abusing their dogs. Because these poor dogs never see beyond the fence and backyard / house. Ok please exercise your dogs they need to explore , smell different scents is important and in fact relaxes a dog . After being out in about with their masters. Exercising your dog takes care of any behavioral situations . That might occur if you don’t exercise them.

I so agree with you! In my opinion, a dog that is left just in the backyard and not taken for walks and dog parks and different outings is essentially a prisoner. I hate people who do that. Bad for all dogs but especially the big ones. I have a Catahoula mix and a rottweiller. I take them to the parks, for walks, home depot and Lowe’s stores and even a Blicks near me that encourages well behaved pets.They have never met a stranger.

My sister and her husband bought a Cane Corso from a breeder who warned them about the difficulty of handling such a big, aggressive breed. (they were used as Roman guard dogs for centuries). they had the dog professionally trained, tried to socialize it, took every step. The dog remained aggressive towards people, and then turned on my sister when she tried playing with it and it wasn’t in the mood. Nearly destroyed her forearm.

The point they’re making here is breed tendencies, not individual dogs. Do you understand the difference?

A good friend of mine breeds St. Bernards and also Cocker Spaniels. She once said that she won’t breed any of her dogs until they are over 4 years old, until she knows their temperment. . Because St. Bs and cockers both were bred for size (in the St. Bs) and coat and bone structure in the cockers. So she waits to see their personality before she breeds them. The only dog that’s ever bitten me was dachshunds.

They should have left rage syndrome out of this. It’s a neurological disorder, not a behavioral one, and the summary does not make that very clear. The dog cannot control it; it’s more like a seizure than actual “rage”. But people who aren’t familiar with dogs and are reading this casually aren’t going to get that. (And I’m not saying cockers won’t bite, but rage syndrome should never have been associated, even by implication, with true aggression.)

Ben Tucker
Guest

This is absolutely true, and there’s another factor.. coat color. According to research the rage syndrome in cockers seems to be connected with coat color (as many traits can be). In the U.S. it’s “blonde” cockers (ASCOB); in the UK IIRC it’s the red ones. A black or parti-color cocker is unlikely to have this problem. There’s also an unrelated issue with temperament in general, not color-connected, that goes back to a hugely popular stud who won the Westminster back in mid century.. he stamped his terrible temperament on an awful lot of cocker bloodlines.

I don’t know why yorkies aren’t on this list. There are very few working terriers which are more aggressive, more controlling and space conscious.

I LOVE Yorkshire terriers and I’ve had several – my best buddy Neko here is the most aggressive of them all (towards other dogs, not toward people) so we’ve just had to limit ourselves / devote ourselves to him for the time being.

I’m not personally acquainted with most of these breeds. German Shepherds, Rottweilers and Dobermans I’ve been around are very trustworthy, gentle dogs. Those reared to be aggressive obviously have the ability to do more damage. If German Shepherds were especially dangerous it would seem they’d be a poor choice as a service dog for the blind. I’ve been bitten a couple of times by a dog. A Scotch Terrier. Give me one of the breeds I mentioned any time. .

Sometimes it’s just the dog. Sometimes it just has a screw loose. I tried for years to break my mother’s Boston Terrier of being an ankle biter. It got to the point where I had to install a different doorbell with an electronic ring because the traditional kind set the dog into a frenzy. Why? No one knows. She was just nuts that way and nothing we did could break it. She remained triggered by bells until the day she died. Luckily, her new Boston is a lot less neurotic.

As a dog groomer of 30 years: Dogs do not act the same when a family member is present as when not. For good or ill. Perfectly loving outgoing dogs with family can act exactly opposite when a family member is not present. Little hellions at home can be model citizens when a family member in not present.

It depends on the Dog…Someone broke into my house and my wolfmalamute chased the person all the way upstairs and cornered them, they crashed through a window and dove off the roof into the Pine tree below–When I got home Quest was standing outside on the roof prowling back and forth..Not all big dogs are a deterrent to crime..but you go sticking your head through a window at my house and your taking your life into your own hands…

I had a neighbor several years ago with a Basenji. They rarely bark, I guess. They came home one evening, the basenji at the door, wagging his tail, happy to see them. And there were bloody handprints all over the walls in the house. A burglar obviously broke in, the dog didn’t bark, And the dog took after the burglar as soon as he got in.

many years ago I owned and showed Lhasa apso’s in the 70’s I owned Am Can Berm Ch OnBa Khabul Khan of Sharbo – top winning Lhasa for 2 years in the country, two years in a row winner of the breed and group placing at Westminster – with owner showing – and I have plenty of scars – the LHASA’S wouldn’t tolerate a growl from another dog – they’d gang up on any dog if there was a fight – It took constant VIGILENCE , and separate fencing to keep my few dogs happy and safe from each other!!!… Read more »

A lot of these little ankle biter dogs are more aggressive than larger dogs. I personally believe some of it has to do with the fact the owners allow it. I have been bit by little dogs in front of the owner and watched the owner act like nothing happened. They think the dog is to small to hurt anyone so do not correct them.
I want to kick these little mutts across a room.

These dogs are trained to be aggressive. It is in their genealogy. Owners of such pets need to be informed as to how to treat these animals. We are the reason for their temperament, therefore we should change them to be more accepted in society it’s not the stereotype of the dog.

Admiral Cochrane in 1814 referred to Americans as Spaniels, which have to be beaten to be made tractable. Unfortunately for him the American “Spaniels” responded to his beating (the burning of Washington) by then biting him twice, first at Baltimore and then at New Orleans.

Lol, not a chance unless you are talking about shoes, cameras, glasses, phones…anything that has your sent on it. These dogs are so non aggressive that I don’t think that rabies would make them mean. In fairness, their baying can get annoying at 3a.m.

My sons have owned beagles. Sweetest breed I ever encountered.Smart too. My most vicious dog was my Chihuahua. My favorite of all dogs owned was my Chow mix. Beautiful dog. Aloof but loyal. He was not all over you like some dogs. I always felt safe with him as a guard dog. He was imposing looking. He only acted aggressively one time when my son’s friend high-fived me. He growled and lunged at the boy but I grabbed his collar and he stood down. A very quiet dog. Grooming was a bear though!

Not really. The only dog who ever bit me, out of the many pits, terriers, Rottweilers, Dobermans, German Shepherds, collies, my own Lhasa Apso, etc was a neighbor’s Dachshund. It’s a little over forty years later and I still have a small scar from it.

You are nuts read the history and record. I used to have your attitude, until my Doberman; which was raised to be a pet and was like a lamb, almost took the ear off of a 4 year old my wife was keeping. The little girl reached out to pet the dog. The dog had been raised around my four sons and all the neighborhood kids. Don’t be a ignorant dog owner, read the history and record of these dogs.

I have a purebred Lhasa Apso that I got from a shelter. He’d been abused and kept on a chain. He was also part of a puppy mill. It took a lot of work to earn his trust and love, but he’s an amazing dog who really is a sweetheart. He loves everyone, even men, and he was scared of men for a long time. He seems to know now that’s he’s something special and revels in it and the attention people are very willing to bestow on him (and believe me, he has no shortage of admirers wherever he… Read more »

All dogs develop a mind of there own and tend to become aggressive when they are young and not given any type of training or socialization. You may even call this neglect.
I think the smarter dog can even learn to call the shots to become Top Dog and the owner becoming the pet.

My Cocker Spaniel, who I loved, was afflicted with “rage syndrome”. I hired a behavior vet to help me with him. She quickly realized that he had the syndrome and trained me to recognize it right before he would attack. But, no way to prevent it. That meant he could never be around children.

my friend’s ‘mini-pincher’ she adopted from a rescue – no bobbed ears or tail and she’s box trained if her ‘mama’ has to work late or the BART train isn’t functioning and she has to bus it home. Very sweet animal – she’ll use the cat’s box in the bathroom when she needs it. I had friends’ who ‘toilet-trained’ their cats with a piece of plastic wrap – the cats just don’t ‘flush’ lol lol

after taking my adolescent psych final (comprehensive) when I finished (got an A for the course) — a fellow student who had adopted a bischon born with one eye convinced the breeder to sell the dog to her to keep her from being put down – so I ‘dog-sat’ while she took her final — was in a figure-8 harness and a leash and I had a bag of treats – she’d sit/down/roll over/beg/shake hands, and even count when one held up the fingers — and her ‘mama’ named her LuLu LOL LOL

We have a lot of allergies in our family, but one breed that we’ve owned that has never caused problems was the poodle. Over my lifetime, between me and my brother and parents, we’ve owned about 4 different miniature poodles. The only one that had a problem with being overly aggressive was our first, and it was only after she had gotten fairly old.and was partly blind from cataracts. Oddly, she was also the smartest of all the dogs we’ve owned, figuring out how to open our sliding door to let her ‘boyfriends’ in (neighborhood dogs who the neighbors stupidly… Read more »

I have a Bullmastiff great pup,listens, he was mistreated by the breeder s son, I got him when he was five months old, they came for a visit he was eight months, would not go near them just barked at them, thought i was giving him back, I guess. Nut I also just got a female Pug, would take on any dog or person, at times sometimes she ignores people but tries to attack dogs, and never blinked an eye when we brought her here with this big Bully.She will steal his treats if he doesn’t watch.

Some of you people have no idea what you are talking about when it comes to dogs. Dogs are DOGS.. They are not human beings.. They have DOG in them and the nature of most breeds is to hunt, protect ( itself or it’s area) and to EAT. The author is CORRECT>. I know they are because I’ve owned many, many, many dogs over my life time and raised many from puppies as well. These dogs don’t have to be mis-treated. You let them get another dog in their space that they aren’t used to having in their space and… Read more »

I’ve owned the top FIVE dogs you mention on this list. Never had a problem! The most dangerous breed: ”humans” who either don’t know what they are getting into when they get a certain breed and therefore don’t care or train it properly OR dog-breeders who are not careful and breed dogs who have negative traits. Yes, some dogs, ANY dog, can be aggressive just like some people are (and some aren’t). Please don’t characterize a breed for the behavior amplified by the media! They never report people getting bitten by Chihuahuas because everyone thinks that’s cute or funny! I… Read more »

Experienced dog owners have learned how to train dogs, it is easy to forget there are people who are first time dog owners and do the wrong things that can cause their pet to be become aggressive. Hear me out, doing things like pulling on their collar to get them off the couch or laughing when a puppy snaps and growls as it is eating rather than correcting the pup, things like that are often the catalysts for later trouble. If you plan to get a puppy, any breed of puppy, please take the time to study dog training. If… Read more »

I don’t have the faintest idea why the author would put beagles on this list. They are very docile creatures and easy to deal with, which is sadly the reason why more than 80% of dogs used in animal testing are beagles. On the flip side, where is the Scottish Terrier?! My favorite breed, I’ve owned four, and I understand the breed extremely well. They were bred to hunt foxes and badgers, and to work on their own, independently of their owners. Which is why they are very difficult to train, need extreme socialization as puppies, and don’t do terribly… Read more »

this post of a Beagle being aggressive borders on the ridiculous.. some of these are accurate on the breeds but, come on.. Beagle.. my guy lying next to me lives to be fed and petted …he gets going if he sees one of the many rabbits that come into our yard.. He can be trusted with small babies sitting in their carriers next to him .. I know this because my Grandchildren were introduced to him immediately he licked their foot. and lay beside the baby and fell asleep..

As a small child, my younger sister sat on the floor and began to play with a Pekinese. We had pets and knew to play gently with them. Suddenly, the Pekinese flew at her face and bit her on the forehead and around the eyes. She had no lasting scars; the wounds were more like scratches. I’ve not liked Peke’s since then and am wary of small dogs in general. I do own a mutt that is beagle and spaniel. Firm handling is the way to go with her. I am the boss.

I have a shih tzu rat terrier mix and a westie maltese mix. Both are beyond sweet. But that is why it’s better to adopt. When I adopted both Henry and Sally they were in foster homes. I knew the dog I was adopting, although they did turn out more wonderful than I was promised.

I agree with everyone here, no dog breed is aggressive without being taught that way, or not trained at all. However, certain breeds do require more experienced owners. Min Pins, for example, did not make this list but are a very stubborn breed. I am a vet tech and rescued one, knowing full well, this breed can be aggressive especially coming from a rescue situation. She has come a long way but I would never leave her in a room alone with a child. Owners must know their dogs and take precautions to keep both others and their dogs safe.… Read more »

I find interesting the remark that we will likely never see a sharpei outside of China. Where I work (for a vet in a relatively small town), I have seen at least two or three sharpei’s, and at least one sharpei mix. We have learned to be very cautious around sharpei’s because they tend to not like to be messed with and WILL snap. One that is occasionally boarded is usually fine when it comes to getting her in and out of her kennel and for walking, but don’t you dare try to open her mouth to give medication, and… Read more »

so incredibly wrong! the top dog in the large and larger size category for dog bites is the Labrador Retriever! did not even make the list! Why? because it is bred for having a soft mouth and families rarely report a non-obvious bite to keep the dog. Most small dogs are very aggressive because people do not put in the time to train them and they were bred for hunting vicious small mammals. more bites come from Dachshunds, JRT, and Chiwahwah than any of the listed breeds! again because people do not report it because the damage is not as… Read more »

I had a look at this web site because I was curious about what types of dogs are most aggressive. Last night my sister and her family were here and a couple of times my Siberian Husky snapped at the two younger girls and my sister was very upset about that. I figured my dog was probably trying to exert dominance over the two younger girls and didn’t mean any real harm. And she didn’t harm them, just scared them a little. The funny thing is, they have a Maltese mix, which is one of the dogs on this list.… Read more »

A dog that is well trained will trust their owner and have no need to rush at another dog. I’ve worked with all breeds of dogs (including so called aggressive breeds) and have never had a problem training the dog to obey and not act aggressively toward anyone. The reason the dog “has a go” at other dogs, is his training. He’s not been trained to obey his walker and doesn’t believe you’re his pack leader. Preferences can be changed with the right training. I’ve rescued many animals that were “unsalvageable” and each one, with the proper training, became loving,… Read more »
