Understanding anxiety in dogs

Rufus has always been a pretty good traveller. After flying from Sydney to Manchester when he was just a year old, jumping in the boot of the car wasn’t a big deal to him.

We changed cars recently and didn't expect it to make the slightest difference. The new one is almost identical to the old one. It's another estate car, his familiar cushioned mat went straight in the back and, from our point of view, nothing much had changed.

Except, during a stop on a longer journey to visit family, I lifted the tailgate to check on him and instead of a relaxed, happy Rufus, he was crouched low on his bed, trembling. He wasn't barking or trying to climb out. He simply looked frightened.

We carried on with the journey and he settled once we arrived, but the following day. Rufus was unusually tired as though the journey itself had exhausted him. That made me wonder whether he'd spent all that time in the back of the car feeling anxious or stressed.

We're trying a few things, including using Adaptil spray to make the car feel more familiar, and hopefully we'll soon discover what settles and soothes him. But researching this made me realise that anxiety isn't something that only affects nervous dogs. Sometimes it appears unexpectedly, even in dogs that have always seemed calm and confident.

Anxiety is more common than many owners realise

When we think of anxious dogs, we often picture those that have had a difficult start in life. Rescue and rehomed dogs can understandably carry emotional baggage from experiences we know little about and they may need extra time, patience and reassurance to learn that the world is now a safe place.

But a confident dog can suddenly become worried by something that seems completely insignificant to us. A different car. A change in routine. Building work next door. A noisy journey. Time spent in kennels. Sometimes there is an obvious trigger. Sometimes there isn't.

Dogs experience the world through senses that are far more acute than our own. A new smell, an unfamiliar vibration, a different engine note or even a change in the way a car moves can completely alter how safe an environment feels to them. What appears almost identical to us may feel entirely different to a dog.

What happens when a dog becomes anxious?

Anxiety isn't a state of mind. It triggers real physical changes throughout the body.

When a dog perceives something as threatening, the brain activates the "fight or flight" response. Adrenaline prepares the muscles for action, while cortisol helps the body stay alert if the perceived danger continues.

This response is incredibly useful in a genuine emergency, but if a dog remains anxious for a prolonged period, those stress hormones stay elevated too. That's why anxious dogs may tremble, pant, pace, struggle to settle or refuse food even when there is no obvious trigger.

It also explains why some dogs seem exhausted afterwards. Remaining on high alert for several hours is mentally and physically demanding. Once those stress hormones begin to fall, many dogs simply need to recover.

Could it be something else?

Sudden anxiety should never automatically be dismissed as a behavioural problem. If your dog develops new fears or becomes anxious seemingly out of nowhere, it's worth discussing it with your vet. Sometimes anxiety is actually a symptom rather than the underlying issue.

Pain, arthritis, hearing loss, deteriorating eyesight, nausea during travel and even the early stages of cognitive decline can all make situations that once felt comfortable suddenly become worrying. Understanding why your dog is anxious is every bit as important as helping them feel calmer.

Helping your dog rebuild confidence

Many anxious dogs improve once the trigger is understood and addressed. Rather than forcing your dog to "get used to it", the aim is to rebuild confidence gradually.

That might mean:

• Keep routines as consistent as possible.
• Introduce new situations slowly.
• Provide familiar bedding or toys.
• Reward calm behaviour.
• Avoid punishment, which often increases anxiety.
• Consider evidence-based calming products if recommended by your vet.
• Keep a diary to see whether patterns emerge.

Every dog is different. What reassures one may do very little for another, so patience is often the most effective tool we have.

Looking after the whole dog

When we talk about healthy ageing at Healthy Happy Dog, we often discuss joints, digestion, heart health or mobility. Emotional wellbeing deserves to be part of that conversation too.

No supplement can cure anxiety, and persistent anxiety should always be investigated properly. But supporting overall health helps dogs become more resilient throughout their lives. Regular exercise, good nutrition, predictable routines and quality sleep all contribute to physical and emotional wellbeing.

Some natural ingredients are also attracting growing scientific interest because of the way they may support normal nervous system function. The mushrooms we use in the Veggie One, Lion's Mane and Reishi, contain bioactive compounds currently being studied for their effects on the brain and nervous system, while brewer's yeast in the Meaty One provides B vitamins that contribute to healthy nerve function.

The science in dogs is still developing, but it reflects a broader principle that we strongly believe in: long-term health is the result of small, consistent acts of care repeated every day.

The little things matter

Not every dog shows anxiety by barking or panicking. Sometimes they simply become quieter. Sometimes they tremble. Sometimes they're just unusually tired the following day. Hopefully we can get to the bottom of whatever is upsetting Rufus and help him cope better with it.

As owners, we can't remove every source of stress from our dogs' lives. What we can do is notice when something changes, respond with patience and make small adjustments that help them feel safe again.
