Genetics, Drives, and Behaviour: Why ‘Fixing’ a Dog Starts With Understanding What They Were Bred For
A better way to frame it
When we talk about “behaviour problems”, it’s easy to focus on what we can see on the surface: barking, lunging, biting, guarding, pacing, spinning, shutting down. But a more accurate (and kinder) way to describe a lot of what we’re seeing is this:
Many dogs aren’t “misbehaving” — they’re expressing unmet genetic needs in an environment that doesn’t fit the dog in front of us.
That doesn’t mean training and rehabilitation don’t matter (they absolutely do). It means we need to widen the lens. Behaviour is shaped by learning, health, stress, and experience — but genetics also plays a role, and it’s one we can’t afford to ignore.
Genetics isn’t an excuse — it’s information
Genetics doesn’t mean a dog is “bad” or “unfixable”. It means a dog comes with a set of built-in tendencies: what they notice, what they’re motivated by, what they find rewarding, what they find difficult, and what they’re likely to do under pressure.
In practical terms, genetics can influence things like:
- Arousal levels (how quickly the dog “switches on”)
- Sensitivity to movement/sound
- Chase, grab, bite and hold behaviours
- Guarding and possession
- Persistence (the dog that doesn’t give up)
- Handler focus (or the opposite — independence)
- Thresholds (how fast they tip into big feelings)
So when we label a dog as “reactive”, “anxious”, “aggressive”, or “difficult”, we need to ask a deeper question:
What was this dog designed to do — and where is that energy going now?
What we see at CBRC: working-line genetics everywhere
At CBRC, around 99% of the dogs who come in for a rehabilitation stay are working-line breeds, or originated from working lines.
These are dogs whose genetics were selected for a purpose. They were meant to have a role. A job. An output.
And now, many of them are living as family pets — loved, cared for, and wanted — but often without the structure and outlets their nervous system is expecting.
That mismatch can show up in loads of ways:
- The dog who can’t settle
- The dog who is constantly scanning the environment
- The dog who explodes at people/dogs/movement
- The dog who becomes controlling or guarding
- The dog who is “busy”, “fizzy”, and always looking for something to do
Sometimes the behaviour we’re trying to change is actually the dog’s attempt to meet a need.
Rehabilitation isn’t just “stop the behaviour”
A good behaviour plan isn’t only about addressing the labelled issue.
It’s also about addressing:
- The environment (what the dog is living in day-to-day)
- The people in the environment (how they move, respond, handle, manage)
- The dog’s role (what the dog believes their job is right now)
- The dog’s outlets (where their drive and energy can go safely)
Because if we only focus on suppression — “don’t do that” — without meeting the underlying needs, we often end up with:
- A dog who looks calmer but is actually bottling it up
- A dog who swaps one behaviour for another
- A dog who improves in one setting but falls apart at home
Outlets: giving the dog somewhere appropriate to put the ‘working’
The good news is we have more options than ever to give dogs healthy, safe outlets.
Depending on the dog, that might look like:
- Scent games (simple, accessible, and incredibly regulating)
- Dog sports (structured work, clear rules, clear reinforcement)
- Mantrailing (a job that uses the brain and the body)
- Enrichment that actually matches the dog (not just “stuff to do”, but the right stuff)
The point isn’t to make every dog into a sport dog.
The point is to build a rehabilitation and behaviour programme that includes the dog’s genetics and needs — not just the human’s expectations.
The open-minded shift that changes everything
If you take one thing from this, let it be this:
Be as open-minded as you can. Bring genetics into the conversation. Bring the dog’s needs into the plan.
When we do that, we stop fighting the dog in front of us.
We start building a life that fits them — and that’s where real, lasting behaviour change lives.
If you’re ‘stuck’ with a ‘behaviour problem’ dog
If you’re living with a dog who feels like a constant project, it doesn’t mean you’ve failed. It might mean you’re trying to solve a genetics-and-needs problem with training alone.
At CBRC, our work is about the whole picture: behaviour, environment, welfare, and the outlets that help a dog feel safe and functional again.
