No, Australian Shepherds are not inherently aggressive; they are loyal, intelligent herding dogs, but their strong protective instincts and high energy can lead to behavioral issues like territorial nipping or reactivity if not properly socialized and trained, with aggression often stemming from fear, anxiety, or lack of exercise rather than innate viciousness. While reserved with strangers, they are loving with family, though their herding drive might make them "herd" children by nipping.
They are not an aggressive dog, but they have a strong desire to protect their family and their territory.
Also called sudden onset aggression, rage syndrome is a neurological disorder, not a temperament defect or training/socialization problem. Affected dogs go into a kind of seizure that makes them attack anyone or anything that happens to be in the vicinity.
Temperament and Socialization
Aussies must also be well socialized to prevent them from developing serious behavior problems, such as being fearful or shy. Such a dog may become a fear-biter, a serious difficulty that can lead to injury of humans and other animals.
Top 20 Least Aggressive Breeds
10 aggressive dog breeds
The "heartbreak breed" refers primarily to the Great Dane, nicknamed this due to their affectionate nature combined with a relatively short lifespan (around 7-10 years) and susceptibility to serious heart conditions like dilated cardiomyopathy (DCM), making losing them particularly difficult for their devoted owners. Other giant breeds like Irish Wolfhounds, Bernese Mountain Dogs, and Saint Bernards also face significant health challenges, including cancer and heart disease, often earning them similar sentiments from owners.
An Aussie that thinks they are the leader within their human “pack” is usually more stressed than they should be, and can even start to “boss” the human members of the household which can lead to uncontrollable behaviour and even inappropriate aggression.
Anatolian Shepherd
These shepherds are independent thinkers with a calm yet assertive demeanor. They form strong bonds with their humans and are naturally protective. While they're not as high-energy as other dogs, they still need plenty of mental and physical stimulation.
The cons of Australian Shepherds include their high energy levels, which require significant exercise and mental stimulation, as well as their tendency to herd, which can lead to nipping behaviors. Additionally, they may be prone to certain health issues and can be challenging for first-time dog owners.
The "3-second rule" for dogs has two main meanings: for greetings, it's a short, sniff-and-separate technique (sniff for 3 seconds, then walk away) to keep initial meetings positive, preventing over-arousal or conflict, and for training, it's the maximum time (3 seconds) to give a dog to respond to a command before repeating it or redirecting, ensuring they connect the action to the consequence. It's also used with petting to give dogs choice: pet for 3 seconds, pause, and see if they solicit more attention.
Most puppies start to calm down around six months to a year. It can take up to two years for them to fully mature and settle. Puppy energy levels can sometimes overwhelm pet parents, but it's all about patience and consistency. As they grow and learn, they'll start to balance out that playful energy.
The safest and most effective way to treat an aggression problem is to implement behavior modification under the guidance of a qualified professional. Modifying a dog's behavior involves rewarding her for good behavior—so you'll likely be more successful if your dog enjoys praise, treats and toys.
Let's take a look at some of the causes of dog biting and dog nipping. Just as the causes are different, what to do about them are different as well. Of particular interest with the Australian Shepherd is their innate herding drive which causes them to nip, especially at moving targets like running children.
While there's no single "number one," the Golden Retriever and Labrador Retriever consistently rank as top friendly dogs due to their gentle, outgoing, and loyal temperaments, making them excellent family pets good with kids and other animals, though they need plenty of exercise. Other top contenders for friendliness include Cocker Spaniels, Beagles, Cavalier King Charles Spaniels, and Pugs, known for their playful, affectionate, and people-loving natures.
They do sometimes tend to pick a favorite person, but are generally affectionate to their entire families. A working dog at heart, the Aussie has a built-in affinity for herding. In fact, he may even try to herd his human pals!
There's no single "number 1" laziest dog, but the English Bulldog is consistently ranked at or near the top for its low energy, love of naps, and tendency to be a couch potato, followed closely by breeds like the Basset Hound, Great Dane, and Shih Tzu, all known for being relaxed companions. These breeds prefer lounging and short strolls over strenuous activity, making them ideal for laid-back owners.
German Shepherd
While not responsible for as many fatalities as pit bulls or Rottweilers, German shepherds are still considered a high-risk dog breed, with considerably more dog bite incidents than most other dogs each year.
Golden retrievers are the ultimate people lovers. They are always looking for a playmate or their next adventure. They are loving and gentle, but also know how to have fun when it's time. Golden Retrievers are great comfort dogs and are always looking to please their owners.
It's a stubborn dog, so its small temperament needs to be controlled from the start to avoid outbursts. The Australian Shepherd is very averse to punishment-based training, and he'll make you understand this. He's much more receptive to training based on reward, listening and kindness.
"Red Flags":
This is especially problematic if it is associated with growling, stiffening of body postures, or a snarling display of teeth. These behaviors indicate fear or pain and should be evaluated to make sure there is not a major underlying problem.
Most all Aussies are protective. It's pretty bred in. In ALL of the herding breeds. Some Australian Shepherds and other herding dog breeds, Border Collies, Collies, etc, have been trained in various protection dog training programs.
Dog Breeds Most Likely to Bite
The "10 10 10 rule" for dogs refers to two main concepts: a potty training method for puppies (10 mins outside, 10 ft space, 10 mins supervision/reward) and the 80/10/10 guideline for raw feeding (80% muscle meat, 10% bone, 10% organ), both offering structure for training or diet. Another interpretation is the 10% rule for treats, limiting them to 10% of daily calories to maintain a balanced diet, ensuring most nutrition comes from complete dog food.
According to Svartberg's data (PDF), a pinscher, a Bernese mountain dog, or an English springer spaniel might be the most disloyal since each ranks very low on playfulness, with moderate sociability.
