When your dog starts scratching excessively without an obvious cause, it can be alarming and frustrating. Persistent itching can impact their comfort, skin health, and overall well-being.
We outline the common reasons why dog itching due to stress occurs, what you can do at home, and when to seek veterinary help.
Dog Itching Due to Stress — Why It Happens
Dog itching due to stress occurs because stress can trigger physical changes in dogs that lead to itching and skin irritation. Anxiety, boredom, or environmental changes can cause the release of stress hormones that alter skin sensitivity and immune responses.
These changes may exacerbate underlying allergies, cause compulsive licking or chewing, and even disrupt the natural skin barrier.
Dogs may also develop stress-induced behaviors like scratching specific spots, leading to sores and hair loss.
Dog Itching Due to Stress: Common Causes
Environmental Changes
A sudden change in a dog’s surroundings—such as moving to a new home, introducing a new pet, or a change in routine—can cause stress.
This stress may manifest physically as increased scratching or licking.
Owners might notice the behavior starts shortly after the change and worsens over time if the stressor remains.
Environmental stress itching is serious because prolonged scratching can lead to secondary skin infections and long-term behavioral patterns that are harder to break.

Separation Anxiety
Dogs that become anxious when left alone may engage in repetitive behaviors, including licking and scratching. This can lead to “hot spots” or raw patches of skin. In some cases, dogs will focus on one area, creating localized sores.
It’s important to address separation anxiety promptly, as ongoing skin trauma can result in chronic skin problems and more severe anxiety over time.
Noise Sensitivity
Loud or unpredictable noises such as thunderstorms, fireworks, or construction can cause acute stress in dogs.
Some may scratch or chew as a self-soothing mechanism. This can happen immediately during the noise or in the hours following it.
Owners should note that these episodes can result in intense, short-term skin damage that requires veterinary care.
Allergic Reactions Exacerbated by Stress
While allergies are a primary cause of itching, stress can make symptoms worse. Dogs with food, environmental, or flea allergies may react more severely when stressed.
The immune system’s overreaction can lead to increased histamine release, making itching more intense.
This creates a cycle where stress worsens allergy symptoms, which in turn increases stress, prolonging the skin irritation.
Boredom and Lack of Stimulation
A lack of physical and mental engagement can cause dogs to develop stress-related habits, including over-grooming and scratching. This is often seen in dogs left alone for long hours without exercise or enrichment.
Without intervention, this can become a compulsive behavior that persists even when the stressor is removed.
Underlying Medical Conditions Triggered by Stress
Stress can aggravate pre-existing skin conditions such as mange or dermatitis. In some cases, it may even trigger flare-ups in otherwise dormant skin diseases.
The scratching can become severe enough to cause open wounds, which may become infected if untreated.
Because the root problem may be medical rather than purely behavioral, veterinary diagnosis is crucial.
What to Do If Your Dog Is Itching Due to Stress
If your dog is showing signs of stress-induced itching, start by identifying and minimizing potential stressors.
Create a calm, predictable routine with plenty of opportunities for exercise and mental stimulation. Providing interactive toys, puzzle feeders, or regular walks can help reduce stress.
Comforting your dog during known stress triggers, such as storms, can also prevent excessive scratching. Use gentle distractions like play, treats, or calming background noise.
Bathing with a gentle, hypoallergenic shampoo may soothe irritated skin, but avoid over-bathing, as it can dry the skin and worsen itching.
In cases of severe or persistent itching, consult your veterinarian for guidance on behavioral training, anxiety management, and potential medical treatments.
When to Call or Visit Your Vet
You should seek veterinary attention if your dog’s itching leads to bleeding, open sores, or hair loss. Persistent itching lasting more than a few days without improvement is also a red flag.
If your dog appears lethargic, loses appetite, or develops signs of infection such as redness, swelling, or foul odor, prompt veterinary evaluation is essential.
For dogs with a history of skin conditions or allergies, any sudden worsening of symptoms should be addressed quickly to avoid complications.
