In today’s fast-paced world, stress is a common issue not only for humans—but also for our pets. Dogs, just like us, can experience both short- and long-term effects from stress. From digestive upset like diarrhoea to immune system suppression, chronic stress in dogs can lead to serious health concerns.
In this article, we'll explore:
Common causes of stress in dogs.
Physical signs and symptoms of stress.
Breeds more prone to stress.
How to help reduce your dog’s stress naturally.
What Causes Stress in Dogs?
Dogs can be sensitive to changes in their environment or routine. Here are some of the most common causes of stress in dogs:
Separation anxiety.
Kennel stays or boarding.
New family members, such as a baby or visiting relatives.
Owner going on holiday – even seeing a suitcase can be a trigger.
Traumatic events, like a dog fight or accident.
Loud noises or phobias (e.g. fireworks, thunderstorms).
Breed predisposition – some breeds are naturally more anxious.
Prenatal or maternal stress, which can affect puppies long-term.
Dog Breeds That Are Prone to Stress
While any dog can suffer from anxiety, certain breeds seem more predisposed to stress-related behavior. Based on clinical experience, breeds like:
Cavalier King Charles Spaniels.
Cocker Spaniels.
Bichon Frise.
Border Collies.
German Shepherds.
...are more likely to display signs of stress or anxiety, especially if not properly socialised early in life.
Tasty Tips
Physical Effects of Stress on Dogs
A small amount of stress is natural. Acute stress triggers the “fight or flight” response through adrenaline. However, chronic stress causes ongoing production of steroid hormones, which can:
Suppress the immune system.
Weaken digestive function.
Disrupt the gut-brain-immune system connection.
Lead to vomiting, diarrhoea, excessive gas, and colitis.
Cause fatigue, low energy, poor coat condition, and appetite loss.
Make dogs more prone to infections and skin problems.
Recent research has uncovered a powerful link between the gut, brain, and immune system in both humans and dogs.
How to Reduce Stress in Your Dog
Fortunately, there are many things you can do to help a stressed dog feel more secure and happy.
Prevention Tips:
Choose a dog that has been well-socialised and raised in a calm home environment.
Ensure puppies are exposed to positive experiences early on.
Stress Management Strategies:
Talk to your veterinarian for a diagnosis and potential treatment.
Use pheromone diffusers, calming sprays, or anxiety wraps.
Consult a certified animal behaviourist.
Provide daily exercise and mental stimulation.
Keep a consistent routine.
Nutrition and Diet:
Some dog foods are formulated to support digestive and emotional health. Look for:
Easily digestible ingredients.
Probiotics or prebiotics.
Natural calming additives, such as L-tryptophan or hydrolysed milk proteins.
Ask your vet about a diet tailored for stress management in dogs.
When to See a Vet
If your dog is showing signs of chronic stress—like frequent diarrhoea, appetite loss, or behaviour changes—don’t delay. Speak with your vet about:
Rule-outs for medical conditions.
Behavioural therapy options.
Medications or supplements if needed.
Final Thoughts
Stress can silently affect your dog’s health, but it doesn’t have to. By recognising the signs early and taking the right steps, you can help your dog live a calmer, healthier life.
