Understanding Stress in Dogs
Stress is a normal part of life for dogs, just as it is for humans. Some breeds, such as Border Collies, Great Danes and German Shepherds, are more prone to stress and neurotic tendencies, especially if they have a history of mistreatment. Stress can be triggered by many factors, including trauma, confinement, changes in routine, boredom, loud noises, travel, new environments, separation from owners, or the arrival of new family members or pets.
When a dog experiences stress, its body undergoes a range of physical changes: the immune system weakens, heart rate and gastric activity increase, hormone levels shift and adrenaline is released for minutes after the stressful event. If stress is repeated or chronic, this can lead to behavioural problems, lowered aggression thresholds and health issues such as allergies, skin problems, poor wound healing, digestive disturbances and recurrent infections of the skin, ears or bladder.
Recognising and Managing Stress Signals
Stressed dogs show many subtle and obvious signs. These can include changes in body posture (stiff or droopy stance, lowered body, pacing, trembling, excessive stretching), altered tail movement, panting, shaking, obsessive behaviours (like tail chasing or excessive licking), whining, barking and yawning. Their eyes may appear glazed, with dilated pupils or “whale eye,” and they might avoid eye contact or repeatedly look to their handler for direction. Other warning signs are lip licking, excessive drooling, furrowed brows, ears held back, scratching, destructive behaviour, restlessness, poor sleep, changes in appetite, weight loss or gain and self-mutilation.
Helping a stressed dog starts with pausing and calming both yourself and the animal. Using calming signals (stretching, yawning, soft eye blinks, looking away) and speaking in a light, reassuring tone can reduce tension. Because chronic stress suppresses the immune system, supporting overall health is essential. Nutritional supplementation with prebiotics, omega-3 fatty acids and key nutrients can help dogs that regularly face stressful situations, such as sporting or show dogs, by supporting their gut health, skin, coat and immune function.
