If your dog gets overwhelmed at the vet, shuts down in new places, or seems wired to react more strongly than other dogs, you are not imagining it. A recent study in golden retrievers suggests that genetics may play a role in fearfulness and stress sensitivity in some dogs. That matters because it supports something many owners already suspect: some dogs are simply more sensitive by nature.

That said, it is important not to overstate the findings. This research was done in golden retrievers, not all dogs. It does not prove there is one “anxiety gene”, and it does not mean every anxious dog is anxious because of genetics. Behaviour is shaped by a mix of inherited traits, health, early life experiences, learning, environment, and day-to-day stress. So the honest takeaway is not “anxiety is genetic full stop”. It is that biology may be one part of the story for some dogs.

The researchers looked at genetic and behavioural data from a large number of golden retrievers and found links between certain genetic regions and behavioural traits including fear of strangers, fear of other dogs, trainability, energy, and aggression. Some of those regions overlap with areas being studied in human psychiatric genetics. That does not mean dogs and people experience anxiety in the same way, but it does reinforce that behaviour is not just about obedience, discipline, or whether an owner “did everything right”.

For owners, that can be reassuring. If your dog struggles with travel, handling, noise, unfamiliar people, or busy clinic environments, it does not automatically mean you caused the problem. Some dogs appear to have a lower threshold for stress. They may become overwhelmed faster, take longer to recover, or react more intensely to situations that other dogs brush off. That does not make them stubborn or dramatic. It means their coping capacity may be different.

It is also worth remembering that “anxiety” is not always a standalone diagnosis. Fear, anxiety, phobias, frustration, pain, cognitive change, poor past experiences, and medical disease can all affect behaviour. A dog that pants, trembles, paces, drools, hides, vocalises, toilets indoors, or becomes snappy may be frightened, overstimulated, sore, confused, or some combination of the above. In older dogs especially, pain or illness can show up first as behaviour change.

That is why a proper medical assessment matters. Behaviour problems are sometimes made worse by arthritis, skin disease, gastrointestinal disease, neurological problems, hormonal disease, or chronic pain. If a dog is already physically uncomfortable, their tolerance for stress drops. In plain English: life feels harder when you hurt. That is one reason anxious dogs should not be dismissed as “just behavioural”.

From a treatment point of view, the goal is not to force a dog through distress and hope they toughen up. Better outcomes usually come from reducing triggers, building predictable routines, using positive reinforcement, and working below the dog’s panic threshold. Environmental management, gradual desensitisation and counterconditioning, enrichment, and in some cases medication can all be part of a sensible plan. Dogs learn best when they feel safe enough to think. Once arousal is too high, learning tends to fall apart.

This is where home visits can help. For many dogs, the clinic itself adds a whole stack of stress before the consult even starts: the car trip, unfamiliar smells, barking dogs, bright lights, slippery floors, waiting rooms, and physical restraint. By the time they are on the consult table, they are already cooked. In-home care removes a lot of those layers. Dogs stay in a familiar environment, handling can be slower and more flexible, and their normal behaviour is often easier to assess.

For Personalised Mobile Vet, that is not a side benefit. It is a core part of how calmer, more useful care happens. A home visit will not magically fix anxiety, but it can reduce pressure enough to make the consult safer, clearer, and less distressing for everyone involved. It also gives more room to look at the full picture: behaviour, pain, mobility, environment, routine, and whether further work-up or treatment is needed.

So what does this genetics research really mean? Mostly this: if your dog is anxious, there may be more going on than poor training or bad luck. Some dogs may be more stress-sensitive from the outset. That does not mean nothing can improve. It means they deserve a plan built around patience, realistic expectations, and proper medical thinking.

If your dog struggles with vet visits, handling, or stress in unfamiliar environments, PMV offers calm, at-home veterinary care designed to reduce pressure and make assessment easier. You can book a visit here: https://www.personalisedmobilevet.com.au
