This is one of the most asked questions we get — and one of the most misunderstood. Most people come in with a strong opinion already formed. Most of the time, that opinion is based on myths. Let’s clear the air and give you the real picture so you can make a decision based on facts rather than folklore.
After 18+ years of breeding Mini Aussies and placing hundreds of puppies into family homes, here’s what we’ve actually observed — in our own dogs and in the feedback we get from families over the years.
The myth worth busting first
Most people requesting a puppy want a “sweet girl” — the assumption being that females are more gentle, docile, and easier to live with. Males are assumed to be dominant, difficult, and prone to marking everything in sight.
This is not accurate. In reality, females in the dog world tend to be the ones who establish and enforce the social order. And spaying or neutering your puppy removes most of the behavioral differences between the two anyway. Read on.
Female Mini Aussies — What They’re Really Like
In the dog pack structure, females typically rule the roost. They determine the pecking order, they enforce it, and they compete to maintain or alter it. This means intact females are actually more likely to display alpha behaviors — including attempting to ride other dogs — than intact males.
Females tend to be more independent, more stubborn, and more territorial than males. They can be more selective about who they choose to bond with and on what terms. They are not unfriendly — they’re just more on their own schedule. As they mature, females tend to develop a quiet dignity about them. They’re affectionate on their own terms and don’t need to be the center of attention every waking moment.
Most inter-dog conflicts — especially serious ones — break out between two females. If you have a female dog at home already, adding another female requires more careful introduction and management than adding a male.
Male Mini Aussies — What They’re Really Like
Males are typically more openly affectionate, more exuberant, and more consistently attentive than females. They want to be near you, they want your approval, and they will absolutely work to get your attention. The words we hear most often from families with our boys: velcro dog.
Males tend to be more steadfast and less moody. What you see is what you get — they’re reliably enthusiastic, reliably affectionate, and reliably silly well into their senior years. Think of the grandpa still playing catch at 70 while grandma observes serenely from the porch. That’s a male Mini Aussie in a nutshell.
Training males is often described as easy because they are highly food-motivated and genuinely eager to please. The caveat is that they can be easily distracted — they want to play, they want to investigate, they want to be in on whatever is happening. Keep sessions short and engaging and they’ll learn fast.
Intact males may mark and lift their leg — this is testosterone-driven behavior that largely disappears after neutering, especially if neutered early. Males neutered before 5 months often never develop the leg-lifting habit at all.
Side by Side Comparison
| Category | Male | Female |
|---|---|---|
| Affection style | Openly and constantly affectionate | Affectionate on her own terms |
| Trainability | Easy — eager to please, food driven | Easy — but more independent |
| Energy / play | Stays playful and silly long-term | Matures and settles earlier |
| Consistency | Very consistent, less moody | Can be more mood-dependent |
| With other dogs | Generally easy-going | Can be territorial with other females |
| Intact behaviors | Marking, leg lifting, roaming | Heat cycles, alpha behaviors |
| After altering | Behaviors largely disappear | Behaviors largely disappear |
| Size | Slight tendency to run larger | Slight tendency to run smaller |
The Real Answer: Spay and Neuter Changes Everything
Here’s the most important thing we can tell you about this decision: once your puppy is spayed or neutered, most of the behavioral differences between males and females become pretty minimal. The heat cycles, the marking, the alpha posturing, the moodiness — most of it is hormonally driven, and removing the hormones removes most of the behavior.
What you’re left with is the individual personality of your specific dog — which is shaped far more by genetics, early handling, socialization, and training than by sex. A well-bred, well-raised male Mini Aussie and a well-bred, well-raised female Mini Aussie are both going to be wonderful dogs. The differences are real but they’re subtle.
What actually matters more than sex: the genetics behind the parents, how the puppy was raised and handled in the first 8 weeks, and what you do with them in the first 6 months. A puppy from a program that prioritizes temperament — raised by a breeder who handles them daily, exposes them to life, and selects breeding pairs for disposition — is going to be a great dog regardless of whether it’s a boy or a girl.
Which One Is Right for Your Situation?
Rather than a blanket recommendation, here are the situations where one might be a slightly better fit than the other:
- ✓You want a dog that is openly and constantly affectionate
- ✓You already have a female dog at home
- ✓You love the playful, puppy energy lasting longer
- ✓You want a reliably consistent, even-keeled dog
- ✓You have kids who want an enthusiastic play partner
- ✓You prefer a dog with a bit more independence
- ✓You already have a male dog at home
- ✓You appreciate a dog that settles and matures earlier
- ✓You want affection that feels earned rather than constant
- ✓You want a slightly smaller dog on average
Our Honest Take After 18 Years
In the end, much of a dog’s character and personality is shaped by you — how you socialize your puppy, how much attention and training you put in, and the environment you provide. Overall, Mini Aussies of both sexes tend to be pleasers, affectionate, and playful. This is one of those rare breeds that genuinely seems like they can read your mind. All they want to do is be with you and enjoy life side by side.
We’ve had families fall deeply in love with our boys who swore they only wanted a girl, and families who came in expecting a male come home with a little girl who stole the show. We’ve learned not to push too hard in either direction — because the right puppy usually makes itself known.
Male or female — you will not be disappointed with this breed. That part we can promise.
Frequently Asked Questions
Are female Mini Aussies more affectionate than males?
Actually the opposite tends to be true. Males are typically more openly and consistently affectionate. Females are affectionate too — but often more selectively, on their own schedule. Neither is better, just different.
Are male Mini Aussies harder to train?
No — males are typically very easy to train. They’re highly food-motivated and genuinely eager to please. They can be more easily distracted by play and activity, but kept engaged they learn fast. Females may be slightly more focused but can also be more stubborn.
Will a male dog mark inside the house?
Intact males may mark, yes. Neutered males — especially those neutered early — typically don’t. Males neutered before 5 months often never develop the leg-lifting habit at all. Marking indoors is a manageable and preventable issue, not an inevitability.
Can two females live together?
Yes, but it requires more careful management than a male-female pairing. Two females are more likely to compete for social rank. It can work well with proper introduction, training, and structure — but it’s worth knowing going in rather than being surprised by it.
Does sex affect size in Mini Aussies?
Slightly. Males tend to run a bit larger and heavier than females within the same litter or pairing — but in the mini size range the difference isn’t dramatic. Both will fall within the normal range for whatever size category they’re from.
Should I let my puppy’s personality guide the decision instead of sex?
Absolutely — and this is actually how we approach matching in our program. We’d rather place the right individual puppy with the right family than insist on a gender preference that might lead to a less-than-ideal match. If you’re open to either sex, tell us about your household and what you’re looking for and we’ll match accordingly.
Curious who’s waiting for you? Every litter has its own mix of personalities — sometimes the puppy that steals your heart isn’t the one you expected.
