At our veterinary clinic, we regularly help clients who are worried about behaviour changes, tummy upsets, or unexpected aggression — and more often than not, stress is the hidden culprit. Here’s what every pet owner should know.
Why Do Pets Get Stressed?
Stress in pets is a normal response to change or challenge, but when it becomes chronic, it can affect their health and happiness. Common causes of stress in both dogs and cats include:
-
Changes in routine (moving house, a new baby, renovations)
-
Separation from their owner or other pets
-
New pets or people in the home
-
Loud noises (thunderstorms, fireworks, vacuum cleaners)
-
Boredom or lack of mental stimulation
-
Conflict with other animals
-
Visits to the vet or groomer
Dogs and cats may respond differently, but the underlying emotional experience is similar — confusion, fear, anxiety, or even depression.
Signs of Stress in Dogs
Dogs are often more outwardly expressive than cats, which makes stress easier to spot — but it can still be mistaken for “bad behaviour” or excitement. Look out for:
1. Panting and Pacing
If your dog is panting heavily when it’s not hot, or pacing up and down restlessly, it could be a stress response.
2. Excessive Barking or Whining
Vocalisation is often a cry for attention or a sign of distress. This is especially common in dogs with separation anxiety.
3. Shaking or Trembling
Shivering in dogs isn’t always due to cold. Fear, nervousness, or stress can cause noticeable trembling.
4. Avoidance or Hiding
If your normally sociable dog suddenly hides under furniture, avoids eye contact, or backs away from people or pets, it’s time to take notice.
5. Changes in Appetite
Some dogs will stop eating altogether when they’re stressed, while others may start scavenging or overeating.
6. Destructive Behaviour
Chewing furniture, digging, or destroying toys may be signs of boredom or anxiety. It’s not “naughty” — it’s often a cry for help.
7. Excessive Shedding
Sudden shedding or dandruff, especially during a stressful event like a car ride or vet visit, can indicate anxiety.
Signs of Stress in Cats
Cats are experts at hiding discomfort. That’s why stress-related issues in felines often go unnoticed until they become serious. Here’s what to watch for:
1. Hiding or Withdrawal
If your cat is suddenly spending more time under the bed, behind the couch, or in closets, they may be trying to escape a stressor.
2. Over-Grooming or Fur Loss
Excessive licking, chewing, or bald patches (especially on the belly or legs) are common signs of feline anxiety.
3. Toileting Outside the Litter Box
Stress can cause even the most well-trained cat to urinate or defecate in inappropriate places — a common sign of environmental stress.
4. Sudden Aggression or Irritability
A previously gentle cat who starts hissing, swatting, or avoiding contact may be under emotional strain.
5. Changes in Appetite
Cats may stop eating altogether when they’re stressed — which can quickly become dangerous. Always seek veterinary advice if your cat refuses food for more than 24 hours.
6. Increased Vocalisation
While some breeds are naturally chatty, sudden yowling, crying, or unusual meows may be a sign of discomfort or fear.
The Physical Impact of Stress
Chronic stress doesn’t just affect your pet’s mood — it can impact their health. Stress hormones like cortisol suppress the immune system, making pets more vulnerable to infections, digestive upsets, and inflammatory conditions.
Stress is also a known contributor to conditions like:
-
Feline lower urinary tract disease (FLUTD)
-
Gastrointestinal issues (vomiting, diarrhoea, constipation)
-
Skin problems (itchiness, licking, fur loss)
-
Behavioural regression (in both cats and dogs)
How to Help a Stressed Pet
Thankfully, there’s a lot you can do to help your pet feel calmer and safer.
– Stick to Routines
Dogs and cats thrive on predictability. Try to feed, walk, and play with your pet at the same time each day.
– Create Safe Spaces
Give your pet a quiet, cozy space where they can retreat when overwhelmed — especially important for cats or nervous dogs.
– Enrichment is Essential
Boredom fuels stress. Provide puzzle toys, scratching posts, snuffle mats, and regular playtime to keep minds busy.
– Use Soothing Tools
There are many vet-approved calming aids, such as pheromone diffusers (Feliway, Adaptil), anxiety wraps, calming treats, or herbal supplements. Ask us what’s right for your pet.
– Minimise Triggers
If you know your pet fears thunderstorms, fireworks, or vet visits, speak to us about preparation strategies — from training techniques to medication if needed.
When to See the Vet
If your pet is showing persistent signs of stress, don’t wait it out — stress rarely resolves on its own. A check-up can rule out medical issues, and we can work with you to create a personalised stress-reduction plan.
At our clinic, we approach stress-related behaviours with empathy, care, and expertise. Whether it’s adjusting your pet’s environment, trying new behaviour techniques, or considering medical support, we’re here to help your four-legged family member thrive.
Final Thoughts
Stress is not always dramatic. Sometimes, it’s subtle — a missed meal, a quiet withdrawal, or a new behaviour you can’t quite explain. But those small signs matter.
By learning your pet’s body language, habits, and emotional cues, you can become their greatest advocate and their greatest comfort. And if you’re ever unsure, don’t hesitate to reach out — your vet team is here to help every step of the way.
Because a happy pet is a healthy pet.
