Most people prefer a dog that is friendly towards other dogs, but they might not end up with such a pup. In fact, one of the most common reasons dog trainers are contacted is because of dog-aggression – an owner with a dog that is aggressive towards other dogs. Although many breeds do indeed enjoy the company of other canines, many do not. All dogs are individuals with their own likes and dislikes, but some breeds were actually bred to be aggressive towards other dogs, so genetics play a big role in their temperament. If you’re looking for a very friendly breed, we suggest you stick to dogs known for being social with other dogs and animals. However, if you don’t mind having an only dog and passing by the dog park without going inside, these breeds might be for you.
#1 – Akita
The Akita is a large, powerful working breed from Japan. They were originally used as hunting, fighting and guarding dogs and their temperament still reflects the characteristics needed for these jobs. Although they are much more docile than they used to be, Akitas are still well-known for being aggressive towards other dogs, particularly those of the same sex. This breed is generally not recommended for the novice owner, but can do very well with anyone willing to accept the Akita temperament as is and put the time and effort into living with a dominant breed.
#2 – American Bulldog
The American Bulldog is derived from the Old English Bulldog, where it was used in the American South as a catch dog and all-around farm dog. Because feral pigs were overrunning the southern portion of the country, farmers needed these dogs to keep the vermin under control. These dogs are deeply loyal to their families but due to their bulldog history, they are known for being aggressive towards other dogs and animals.
#3 – Chow Chow
The Chow Chow comes from northern China where it was used as a general purpose working dog – herding, hunting, guarding and sled pulling. This breed is very loyal and attached to its human family, but does prefer to be the only dog. Chow Chows need to be socialized very well from early on in their lives as they do have a tendency to be aggressive towards both people and other dogs and animals.
#4 – Dogo Argentino
The Dogo Argentino was developed in Argentina as a fighting dog and big-game hunting dog. Although the dogs have been bred to have more docile temperaments in recent years, they are still expected to be aggressive towards dogs and other animals. Although attacks are rare when the dogs are supervised, it is still recommended not to keep this breed alone with other animals. Thankfully, dog fighting has long been illegal and those using them as catch dogs need their Dogo Argentinos to be social around other dogs since they are hunting in groups. This has helped create a Dogo with a much more social temperament.
#5 – Irish Terrier
The Irish Terrier is one of the oldest of the terrier breeds. Originally bred for hunting, they enjoy the company of people and make great performance dogs. However, because of their terrier history, they should not be trusted around other dogs or animals. Irish Terriers are known for being aggressive towards other dogs, but early socialization and training will keep accidents at a minimum. Today, the Irish Terrier makes a great active companion.
#6 – Miniature Pinscher
Despite their size, Miniature Pinschers are generally not recommended for novice owners because of their aggression towards other dogs and animals. They are assertive, independent and outgoing dogs that can do well in various dog sports and need a lot more exercise than their size implies. They are very playful with their human families, however, and make great companions for adults and older children.
#7 – Schipperke
The Schipperke is a tenacious farm dog from Belgium, with a lot of personality packed in its tiny body. They are mischievous, stubborn and strong-willed dogs often nicknamed “little black devils” by their enthusiasts. They are known for being aggressive towards other dogs, but make excellent active companions for someone looking for a smaller breed to keep them on their toes. Although not recommended for the novice owner, they can do well with the right person willing to put in the right time and effort.
#8 – Tosa Inu
The Tosa Inu is a large Mastiff-type breed from Japan. This breed was originally bred exclusively as a fighting dog and it is still used for this disquieting sport is still legal and fully functional. Because of this, they are extremely dog aggressive as their sole job requires this characteristic. Unfortunately, this breed is quite rarely found and also banned in many countries outside of Japan because of its fighting history. We hope one day that the dog fighting legality in Japan will end and that this breed can be left to fall extinct or bred into a more social, happier life.
