10 Most Aggressive Dog Breeds - Temperament Ratings and Information
Don't Come Any Closer!
List of Dog Breeds You May Not Want for the Family Pet
Have you ever wondered which dog breeds are the most aggressive? Maybe you are looking to get a new puppy for the family pet and would like to know which dog breeds may not be the best with children. After doing much research, I have compiled a list of the 10 most aggressive dog breeds.
In doing my research I have found that different organizations as well as different “experts” have their own opinions as to which dog breeds are the “most aggressive”. The ratings, as far as which is the most aggressive, vary as well. The dog breeds that I have listed here are the breeds that have been ranked as the most highly aggressive, most frequently. The percentage of the test results I have included are from the American Temperament Test Society. I don’t know that I agree with the per centage findings here, I would prefer if the same number of dogs per breed were tested, but I am not the “expert”.
#1 - Chihuahua
Chihuahua - 41 tested, 28 passed, 13 failed = 68.3%
The chihuahua is the smallest breed of dog registered with the American Kennel Club. They are also known as being the smallest dogs in the world. They are included in the toy group of dogs and range from 4 to 6 pounds. They can have either short or long hair. The chihuahua can come in just about any color and their coloring can be either solid, marked or splashed. The chihuahua is considered to be the oldest dog breed in America. The chihuahua originated in the Mexican state of Chihuahua, thus it’s name. It was introduced in Europe, by the famous explorer, Christopher Columbus. Chihuahuas are very loyal and devoted to their owners but generally one or two person dogs. They can be devoted to the point of jealousy and may bite or snip at someone coming too close to their owner.They are very temperamental and are not known as child friendly dogs. Because they do not like strangers, they bark often and can be good for alert style watch dogs.
#2 - Dachshund
Dachshund-(Standard Smooth Haired) - 48 tested, 33 passed, 15 failed = 68.8%
The dachshund is listed in the small dog breed and is included in the “hound” group by the AKC. They can range in size from 8 to 32 pounds. The dachshund can come in both long and short hair and can be any color. The dachshund originated in Germany in the 17th century and was used primarily to hunt badgers. They were on the verge of extinction after World War I, but are now one of the most popular dogs in America. The dachshund is susceptible to “Small Dog Syndrome”, which basically means that it tries to make up for it’s small size, with a large attitude, which can lead to behavioral issues. If socialized at an early age, they do well with children, but does not do well with too much rough play. Take caution with small pets such as mice, rats, hamsters, etc. as they have a strong hunting instinct toward this type of animal.
#3 - Chow Chow
Chow Chow - 98 tested, 70 passed, 28 failed = 71.4%
The chow chow is listed as a medium size dog in the “non-sporting” group with the AKC and can weigh between 45 and 70 pounds. They have a long haired thick coat and can come in red, black, blue, cream or cinnamon colors. The exact origin of the chow chow is not known but it is believed that they originated thousands of years ago in either China or Mongolia. It is known that they were most often used as hunting and herding dogs. They became popular in the US during the 20th century when President Calvin Coolidge owned one as a pet. The chow chow is a dominant personalitied dog and can become assertive at times. Because of their assertiveness, they are not recommended for first time dog owners. Strong guidance and firm training are required to have a well mannered dog. It has been noted that they do not have a good peripheral vision and can be startled easily.

The Doberman Pinscher is listed as a medium sized dog in the “working” group by the AKC and ranging in size from 70 to 90 pounds. They have a thick, glossy short haired coat which can be red, black, blue or fawn in color. The origin of the Doberman goes back to Germany, where a man by the name of Karl Louis Doberman is credited with developing this breed. He worked as a tax collector and wanted a dog that he could take with him for protection on his visits to the more dangerous areas he traveled. The Doberman is a very intelligent dog and has been used mainly for guard dogs and police work. They have a very strong, protective instinct toward their masters, but if raised with strong leadership and good owners, they can be good with children as well as other dogs.

The dalmation can be reserved with other dogs and needs to be socialized at an early age. They are good with children but if not given enough attention by their master, can have some behavioral issues. They are very energetic dogs and need a good place to release some of this energy.

It was first known as “Rottweil Butcher’s Dog” and later shortened to rottweiler. In the earlier days they were used for cattle herding and bear hunting, among other things and became popular in the US as guard dogs and worked with the Army and police forces. The rottweiler can be rather aloof and does not accept strangers easily. They are very loyal and protective of their owners and will defend their home “area”. They are normally good natured with children but because of their size and energy level are not recommended for families with very small children.
Jack Russell Terrier
#7 - Jack Russell Terrier
Jack Russell Terrier - 63 tested, 53 passed, 10 failed = 84.1%
The Jack Russell terrier breed is not recognized by the AKC due to opposition of the breeds parent societies which have resulted in the recognition of the Parson Russell terrier. The Jack Russell terrier and the Parson terrier are basically the same breed with minor differences. The Jack Russell is a small sized dog and range in size from 14 to 18 pounds. They are predominantly white in color with black or tan markings. Their can either have a short haired, long haired or broken coat. The term “broken” meaning a coat of both long and short hair. The Jack Russell’s origin begins in England where they were primarily used for fox hunting. They have also been used in groundhog, badger hunting. The “Russell” terriers are all very energetic and stubborn dogs. Because of such enormous energy, they have little patience and are not very tolerant with children.
#8 - German Shepherd
German Shepherd - 3,133 tested, 2,651 passed, 482 failed = 84.6%
The German Shepherd is a medium size dog included in the herding group of the AKC. Their size ranges between 70 and 85 pounds. The German Shepherd breed began in Karlsruhe, Germany in the 1800's. During WWI, they were used as military dogs by both the German and French military. They do not take to strangers well and therefore make good guard dogs. They are very intelligent dogs and were the first dog breed to be used as a guide dog for the blind. They are also used often in search and rescue teams as well as police and narcotic dogs. The German Shepherd has become one of the most popular dogs in America. Every thing I have researched tells me that this dog is good with children. As long as they are not trained as guard dogs, I, personally, do not see that the German Shepherd is an “aggressive” breed.
American Staffordshire/Pit Bull Terrier
#9 - American Staffordshire/Pit Bull Terrier
American Staffordshire Terrier/Pit Bull Terrier - 839 tested, 728 passed, 111 failed = 86.8%
The American Staffordshire Terrier is also know as the American Pit Bull Terrier. They are a medium sized dog included in the terrier group and can weight between 55 to 65 pounds. The American Staffordshire Terrier originated in England, in the Staffordshire region, thus it’s name. The first strain of this breed was designed for use as guard dogs and dog fighting and were bred for stronger, stockier frames. When the breed was brought to America and dog fighting became banned, there was a second strain of this breed developed. It is a more mild mannered, smaller framed strain. This strain can is very loyal and protective of it’s owner and family. This strain is also known for being very good and patient with children. Just be sure you do a little background check on this dog before you choose it as a family pet.
#10 - Siberian Husky
Siberian Husky - 298 tested, 259 passed - 86.9%

In all my research and having owned 4 Siberian Huskies, I cannot find where they have an aggressive personality. The Huskies do tend to be territorial and do not always get along well with other dogs, but are usually good with children.

- Pit Bull Dog Heroes
There are good and bad dogs in any breed. It all depends on how the dog is treated and trained. I'm going to share some positive stories about the pit bull dog and show how truly heroic they can be.
Again, this is information that I have compiled from many sources as well as some personal experience. Not to say that any of these dog breeds would not make good family pets, given the right owners and training. Because training, or the lack of training and how the dog was previously treated, can make a huge difference in the personality of any dog, doing some type of “background check” on the dog would be a good idea.
