Are Blue Heelers (Australian Cattle Dogs) aggressive

It is unfair and inaccurate to say that a Blue Heeler is an aggressive breed of dog. The breed is supposed to be suspicious towards strangers, but they should not be aggressive towards them. What is often perceived as aggression is their natural protective and controlling herding instinct. This can still be a behavior issue but should be dealt with differently.

Every dog is an individual and some Australian Cattle Dogs are aggressive which is true of any breed of dog. The reason for the aggressive behavior of an individual Blue Heeler is not so much a trait of the breed but likely the result of their past. In some cases, it may be the result of bad breeding. It is the old nature vs nurture debate.

What is and is not aggression in Blue Heelers

It is also important to distinguish between aggressive behavior and behavior related to their instinctive herding drive. Blue Heelers can have a reputation for biting when in reality they are nipping. This is still not acceptable behavior but it is not aggression. It is more a dominant and controlling behavior.

Nipping is a hard-wired herding trait of the breed using it to nip at the hocks of cattle to get them moving. You can’t train an instinctive natural behavior out of a dog but you can control and redirect it. This can be achieved through training, socialization, and providing enrichment activities that cater to their herding instincts such as herding balls.

The Blue Heeler is also very loyal and becomes attached to members of their family and can be extremely protective of them. As a result, they can be overprotective of you when people the dog doesn’t know do anything they see as threatening. This protective nature of the Australian Cattle Dog often makes them very good guard dogs. To learn more about Blue Heelers as guard dogs see here.

So it is important when dealing with what is perceived to be an aggression issue with a Blue Heeler that you determine if it is actual aggression or their instinctive protective nature. Both behaviors can be an issue, but the approach to solving them is different.

What is aggression in dogs

Actual aggression by a dog can be defined as an unprovoked and forceful attack. What is considered unprovoked will depend on the situation. If a dog runs up to a person for no reason and bites them then that is an unprovoked attack. If a person or another dog attacks you and your dog attacks them to protect you it is a different matter.

What a dog perceives as being provoked does not always align with what is acceptable to us.
