When your dog is shaking and hiding, it’s more than just unusual behavior—it’s often a clear sign that something is wrong. Dogs typically hide when they’re scared, anxious, unwell, or in pain, and when this behavior is paired with trembling, it’s important to pay attention.
We outline the common causes of dog shaking and hiding, what you can do at home, and when to seek veterinary help.

Dog Shaking and Hiding — Why It Happens
Dogs shake and hide when they feel frightened, sick, or in pain, or when they are responding to a stressful environment or internal discomfort. This combination of behaviors often points to a physical or emotional trigger that needs to be addressed to keep your dog safe and comfortable.
Common Causes of Dog Shaking and Hiding
Anxiety and Fear
Loud noises, thunderstorms, fireworks, or unfamiliar guests can make your dog retreat and tremble in fear.
Dogs with general anxiety or noise phobia may shake, drool, or run to hide under furniture or in closets.
This behavior can escalate over time if not managed with desensitization, calming tools, or medications.
Comforting your dog, using anxiety wraps, or creating a safe space may help reduce their stress.
Illness or Physical Pain
When dogs don’t feel well, they may seek solitude and tremble from discomfort.
Common culprits include gastrointestinal upset, pancreatitis, or internal organ issues.
Look for additional symptoms like vomiting, diarrhea, lack of appetite, or lethargy.
Dogs in pain may also avoid contact, growl when touched, or show subtle signs like lip licking or restlessness.

Injury or Orthopedic Conditions
A soft tissue injury, joint strain, or even a slipped disc can cause pain that leads a dog to hide and shake.
You might notice limping, difficulty standing, or reluctance to be handled.
Dogs may isolate themselves instinctively to avoid interaction that might worsen their pain.
Veterinary examination is necessary to assess the injury and begin proper treatment.
Neurological Disorders
Shaking combined with hiding could indicate a neurological issue such as a mild seizure, vestibular disease, or early stages of cognitive dysfunction.
Dogs may seem confused, uncoordinated, or overly sensitive to light and sound.
If your dog has a history of seizures or you observe head tilting, circling, or pupil changes, a neurologic cause should be considered.
These cases often require diagnostic imaging and long-term management.
Toxin Exposure
Ingesting something toxic—such as chocolate, xylitol, grapes, or household chemicals—can cause trembling, drooling, and fear-based behaviors.
Dogs might hide because they feel sick or overwhelmed by neurological effects.
Other symptoms can include vomiting, diarrhea, disorientation, or collapse.
If you suspect poisoning, get emergency veterinary help immediately.
What to Do If Your Dog Is Shaking and Hiding
Remain calm and avoid forcing your dog out of hiding. Sudden movements or loud voices can increase fear.
Offer a quiet, comfortable space where your dog feels safe, such as a crate or darkened room.
Check for other signs of illness or injury, including vomiting, limping, or signs of distress.
Avoid punishing or scolding the behavior—it’s your dog’s way of coping with discomfort or fear.
Call your vet for advice, especially if this behavior is new, intense, or accompanied by physical symptoms.
When to Call or Visit Your Vet
You should contact your veterinarian if your dog:
Suddenly starts shaking and hiding without a clear trigger
Shows signs of pain, illness, or injury
Has tremors that last more than a few minutes
Refuses to eat, drink, or move for several hours
Has a history of anxiety or seizures and shows new behavior changes
Prompt evaluation helps identify the root cause and ensures your dog receives the appropriate care.

Key Takeaway
When your dog is both shaking and hiding, it’s a sign that they’re feeling deeply unwell—physically or emotionally.
Create a calm environment, watch closely for symptoms, and involve your vet to rule out pain, illness, or more serious issues.
The sooner you act, the sooner your dog can feel safe, comfortable, and secure again.
